Answer:

kinetic energy is needed for potential energy since without kinetic energy potential energy would not have the potential energy to do anything

sorry if it doesn't make sense

Explanation:

youre holding a ball in the sky that is potential energy since it has the potential to fall. the kinetic energy is when it falls and lastly the potential is when it hits the floor..

The combination of a particle's mass and velocity produces momentum. Momentum is a vector quantity that has both magnitude and direction. The force exerted on a particle is equated to the time rate of change of momentum by Isaac Newton's second equation of motion.

First law of Newton : According to Newton's first law of motion, if a body is at rest or moving in a straight path at a constant speed, it will stay in that state or continue to move in that direction unless it is acted upon by an outside force.

Second law of Newton : According to Newton's second rule of motion, a body's rate of momentum change is inversely proportional to the force acting on it, and momentum changes occur in the direction of the net applied force.

Third law of Newton : Newton's third law of motion states that there is always an equal and opposite reaction to every action.

In order to accomplish work and to produce heat and light, energy must be transferred to a body or to a physical system. Energy is the quantitative attribute that does this.

A push or pull that an object experiences as a result of its interactions with its environment is known as a force.

Dust and smoke rising in the atmosphere as a result of an asteroid impact hinder sunlight from reaching our planet, resulting in a decrease in global temperature. Many living beings could die as a result of this incident. A small city might be destroyed if an asteroid the size of an apartment strikes Earth. A 20-story building-sized asteroid might wipe out a small nation if it were to strike Earth.

Answer:

its B

Explanation:

It's B & A at the same time because A. a roller coaster uses brakes to slow down and stop. B is the most reasonable answer. Because all roller coasters go up and over a second time over the hill, but they also slow down. But go with B.

Answer:

The force formula is defined by Newton's second law of motion: Force exerted by an object equals mass times acceleration of that object: F = m×a( force = mass×area)

Speed, distance and time can be calculated using a magic triangle. D (the distance) goes in the top of the triangle, S (speed) goes in the bottom left of the triangle and T (time) goes in the bottom right of the triangle.

Answer:

The answer is B.

Explanation:

A Block has a density of 0.97 g/cm 3. That is why 97 percent of the ice will sink in below the water.

Explanation:

At first it is in 14m position but position doesn't matter in displacement, similar case for time taken.

So at first it travels 6m in positive direction.

So displacement= 6m

Then it travels 13 in opposite or negative direction.

So displacement = 6 -13 m = -7 m

Explanation:

Answer:

122.5 meters

Explanation:

We have the third equation of motion:

[tex]\boxed{\mathsf{v^2=u^2+2aS}}[/tex]

Here, the particle is a flare.

It's initial velocity is 49 m/ s and the final will be zero, that's 'cause the particle comes to a standstill upon reaching its maximum, in case of motion under gravity.

a will be the acceleration due to gravity = 9.8 m/ s²

So, here are the terms we've got for the third eqn. of motion:

Now, the term we've got to find out is the height reached by the flare, i. e., S.

=> v² = u² + 2aS

=> (0)² = (49)² + 2×(-9.8)×S

=> 0 = 49×49 - 2×9.8×S

=> 2×9.8×S = 49×49

[tex]\implies \mathsf{S=\frac{49\times 49}{2\times9.8} }[/tex]

=> S = [tex]\frac{245}{2}[/tex]

And, S is the maximum height the flare covers, so the answer is 122. 5 meters

From the information provided, the velocity after 2 seconds is  11 m/s.

From the equations of motion;

v = u + at

Where;

v = final velocity

a = acceleration

t = time taken

The initial velocity of the bike was 7 m/s and its acceleration is  2 m/s2. This change occurred within a time of 2 seconds.

Hence;

v = 7 + 2(2)

v = 11 m/s

The velocity after 2 seconds is  11 m/s.

We have that the instantaneous velocity of the shuttlecock when it hits the ground is

[tex]V_{int}=\sqrt{U^2+19.6H}[/tex]

From the question we are told

Assuming the acceleration is still -9.81 m/s2, what is the instantaneous velocity of the

shuttlecock when it hits the ground? Show your work below.

Generally the equation for acceleration  is mathematically given as

[tex]a=v \frac{dv}{dx}\\\\\Therefore\\\\\2ah=v^2-u^2[/tex]

Where

acceleration is still -9.81 m/s2,

Hence,

[tex]V^2-U^2=2(-9.81)*-H[/tex]

Therefore

[tex]V_{int}=\sqrt{U^2+19.6H}[/tex]

The speed of the ball when it returns to the same horizontal level is 8 m/s.

The given parameters;

During the motion of a projectile, the speed of the projectile reduces as the projectile moves upwards and eventually becomes zero at the maximum height.

As the projectile moves downwards, the speed of the projectile starts to increase and it will become maximum (equal to the initial speed) before the projectile hits the ground.

Thus, we can conclude that the speed of the ball when it returns to the same horizontal level is 8 m/s.
