Answers

Answer 1

Answer:

KE = [tex]\frac{1}{2}[/tex] m[tex]v^{2}[/tex]

Explanation:

In the generation of energy from hydroelectric power station, the motion of water, and the turbines are paramount. The falling flowing water turns the blades of the turbine, which in-turn causes the movement of a coil within a strong magnetic field.

The motion of the coil which cuts the strong magnetic field induces current. Thus, the system generates electrical energy.

The equation that links kinetic energy (KE), mass (m) and speed (v) can be expressed as:

KE = [tex]\frac{1}{2}[/tex] m[tex]v^{2}[/tex]

What is the acceleration of a racing car if it's speed is increased uniformly from 44 m /s to 66 m / s over an 11 second period ?

Answers

Answer:

the acceleration of the race car is 2 m/s²

Explanation:

Given;

initial velocity of the race car, u = 44 m/s

final velocity of the race car, v = 66 m/s

time of motion of the race car, t = 11 s

The acceleration of the race car is  calculated as;

[tex]a = \frac{v-u}{t} \\\\a = \frac{66-44}{11} \\\\a = 2 \ m/s^2[/tex]

Therefore, the acceleration of the race car is 2 m/s²

A 13.0km bucket is lowered vertically by a rope in which there is 170N of tension at a given instant. Determine the magnitude of the acceleration of the bucket. Is it up or down?

Answers

Answer:

13.07m/s2 down

Explanation:

I think the equation would be

Fnet/m=a

since tension is the only force mensioned that means that

170N/13.0kg=13.07 m/s2 down

acceleration is down

Not really understanding this, wouldn't mind some help. : )

Answers

Explanation:

Given

Mass (m) = 1200 kg

Acceleration (a) = 3 m/s²

Force (F) = ?

We know

F = m * a

= 1200 * 3

= 3600 Newton.

Therefore the force acting on the car is 3600 Newton.

Please help me please I need someone to help me with all this question 1) How do we calculate the momentum of a race car? What part of this changes during a collision? 2) What happening to the momentum of the car when they crash? 3) how does impulse factor into this? 4) what type of collision is it ( ideally) when cars crash into this SAFER barrier?

Answers

Answer:

Explanation:

1 ) Momentum of a race car = mass of car x velocity of car . During a collision , an external  force acts on the car which changes the momentum of the car in the direction in which force acts .

2 )

The momentum of the car decreases as external force acts against the momentum . Sometimes when external force is very high , direction of momentum  is reversed .  

3 ) Impulse is force x time of action of force . Generally time of action of force in large collision  is very small . so it is calculated very carefully .

Impulse = change in momentum .

4 ) The type of collision is inelastic . In this type of collision , car crashes into safer barrier , sticks to it . It does not rebound from the barrier . In case of elastic collision , rebound creates large impulse creating huge damage to the car .
