1. A 1,000kg car is moving at 20m/s. What is it's momentum?
2. The momentum of a car is 50,000kg.m/s that travels at a velocity of 25m/s. What is the mass of the car?
3. A ball was gifted by a bat. The impact force is 250N, and the contact time is 0.2s. What is the impulse received by the ball?
4. The momentum of a car is 30,000kg.m/s. The mass is 1,500kg. What is it's velocity?

Answer:
Using the formula:
1/2*Mass*(Speed)^2
We can do it step by step but for now lets assign a variable to the kinetic energy like x. Since we are trying to find x let’s do the equation.
1/2*1,000Kg*(20m/s)^2= x
1/2*1,000Kg*400m/s= x
500Kg*400m/s= x
200,000 = x
