Suppose that the net external force (push minus friction) exerted on a lawnmower is 51 N. parallel to the ground. The mass of the mower is 24 kg. What is its acceleration?
Answer:
2.125 m/s^2
Explanation:
Use Newton's second law: Force equals mass times acceleration, F = ma. You know the force (51 N) and you know the mass of the mower (24 kg). Remembering that a Newton is the same as kg-m/s2, solve for acceleration:
F = ma
51 kg-m/s2 = 24 kg * a
2.125 m/s2 =a
If a net external force of 51N is extorted on a 24kg lawnmower parallel to the ground, the acceleration of the mower will be 2.125 m/s².
Given the data in the question;
Net External Force; [tex]F = 51N[/tex]
Mass of the Mower; [tex]m = 24kg[/tex]
Acceleration; [tex]a = ?[/tex]
To determine the acceleration of the mower, we make use of the equation from the Newton's Second Law of Motion:
[tex]F = m\ * \ a[/tex]
Where F is the force exerted, m is the mass and a is the acceleration.
But then, we know that; ( A newton is the same thing as [tex]1 kg.m/s^2[/tex] )
Hence, Our Net External Force; [tex]F = 51kg.m/s^2[/tex]
We substitute our values into the equation to find acceleration "a"
[tex]51kg.m/s^2 = 24kg\ *\ a\\\\a = \frac{51kg.m/s^2}{24kg} \\\\a = 2.125 m/s^2[/tex]
Therefore, If a net external force of 51N is extorted on a 24kg lawnmower parallel to the ground, the acceleration of the mower will be 2.125 m/s².

A hockey stick strikes a hockey puck of mass 0.17 kg. If the force exterted on the hockey puck is 35.0 N and there is a force of friction of 2.7 N opposing the motion. what is the acceleration of the hockey puck?
Choices:
0.0054 m/s^2
0.005 m/s^2
200 m/s^2
190 m/s^2
Answer:
[tex]a=190\ m/s^2[/tex]
Explanation:
Mass of a hockey puck, m = 0.17 kg
Force exerted by the hockey puck, F' = 35 N
The force of friction, f = 2.7 N
We need to find the acceleration of the hockey puck.
Net force, F=F'-f
F=35-2.7
F=32.3 N
Now, using second law of motion,
F = ma
a is the acceleration of the hockey puck
[tex]a=\dfrac{F}{m}\\\\a=\dfrac{32.3}{0.17}\\\\a=190\ m/s^2[/tex]
So, the acceleration of the hockey puck is [tex]190\ m/s^2[/tex].
The magnitude of acceleration of the hockey puck is 190 m/s² .
Given data:
The mass of hockey puck is, m = 0.17 kg.
the magnitude of external force on the puck is, F = 35.0 N.
The magnitude of force of friction is, f = 2.7 N.
We need to find the net force acting on the puck first. For that consider the applied force in the x-direction. Then net force is,
F' = F - f
Solving as,
F' = 35.0 - 2.7
F' = 32.3 N
Now, use the Newton's Second law to obtain the magnitude of acceleration (a) as,
F' = ma
Solving as,
32.3 = 0.17 (a)
a = 32.3/0.17
a = 190 m/s²
Thus, we can conclude that the magnitude of acceleration of the hockey puck is 190 m/s² .

In the winter, people often buy large bags of rock salt to sprinkle on their walkways. Why do people do this?
Answer:
It helps melt the ice away on their walkway.
Explanation:
The salt makes the ice to freeze at a lower temperature. So when a solute (salt) comes into contact with the ice the freezing point is lowered.

Which statement about mass and inertia is not true?
A. Both mass and inertia play a role in Newton's first law.
B.Mass is a quantitative measurement of inertia.
C. The tendency of an object to remain at rest results from a property called inertia.
D.Newton's first law is sometimes called the relative inertia law.""
Answer:
D. Newton's first law is sometimes called the relative inertia law.
Explanation:
Newton's first law of motion states that an object at rest will stay at rest and that in motion will stay in motion with same speed and in the same direction unless an unbalanced force acts on it. It is also called the law inertia. Mass and inertia play a role in this law because mass is a quantity that mainly depends on inertia in that a body with more inertial will exhibit more mass.

A student is standing on a very steep hill, kicks a soccer ball horizontally with a speed of 10 m/s toward a student who is sitting on a level field 3 meters below. How long does it take the soccer ball to strike the ground?
Answer:
0.782 seconds
Explanation:
We are given that the ball starts out on a hill that is 3 m above a level field below. And that the ball is kicked horizontally. We are asked how long the ball takes to hit the ground 3 meters below.
On closer consideration of the given situation, it is important to realize that even though the ball starts out with a speed of 10m/s in the horizontal direction, that this will not make a difference in how fast the ball travels in the vertical direction (which is what the question is basically asking for). Hence for this question, we can ignore the initial horizontal speed of the ball and realize that the initial vertical speed is 0 m/s.
Recall that one of the equations of motion can be expressed as:
s = ut + (1/2) at² (refer to attached for reference)
where,
Applied in the vertical direction,
s = vertical distance travelled = 3 meters in this case
u = initial vertical velocity = 0 m/s in this case
a = acceleration due to gravity, g = 9.81 m/s²
t = time taken ( we are asked to find this)
simply substituting the known values above into the equation:
s = ut + (1/2) at²
3 = 0 + (1/2) (9.81)t²
3 = 4.905t²
t² = 3 / 4.905
t² = 0.61162
t = √0.61162
t = 0.782 seconds
