Linear Momentum
A 5 kg bowling ball is rolling down the lane with a velocity of 2 m/s. What is the magnitude of its linear momentum?
An object of mass has a velocity . What is the correct expression for its linear momentum ?
A car of mass 1000 kg is moving to the right with a velocity of 20 m/s. What is the direction of its momentum?
A constant force of 20 N is applied to an object for 5 seconds. What is the impulse on the object?
A 2 kg ball initially at rest is struck with a force of 10 N for 0.1 seconds. What is the change in momentum of the ball?
A 0.5 kg ball moving at 10 m/s hits a wall and bounces back with a velocity of -8 m/s. If the contact time is 0.05 s, what is the average force exerted on the ball by the wall?
A 2 kg object's velocity changes from 10 m/s to 15 m/s over a period of 2 seconds due to a constant force. What is the magnitude of this force?
