Changes In Momentum (physics Only) (GCSE Physics)

A constant resultant force of 120 N acts on a 4.0 kg object for 2.0 s. What impulse does the force produce?

A 4.0 kg cart moving at 2.5 m/s collides elastically with a 1.0 kg cart moving toward it at 1.5 m/s. What is total momentum before collision? (Take right as positive)

A 0.20 kg ball hits a paddle and stops in 0.02 s. The average force on the ball is 150 N opposite to motion. What was the ball’s speed immediately before impact?

A 0.50 kg toy car is moving at 4.0 m/s. What is its momentum?

A 5.0 kg object accelerates from 2.0 m/s to 12.0 m/s in 4.0 s. What average force acted on it?

A 0.8 kg ball is moving right at 10 m/s and strikes a wall, reversing to left at 6 m/s. If contact time is 0.04 s, what average force acted on the ball (magnitude)?

Which statement about impulse is correct?

A 2.0 kg object moving at 3.0 m/s collides with and sticks to a 3.0 kg object at rest. What is their common speed immediately after collision?

Which equation correctly links force (F), time (?t) and change in momentum (?p)?

A lorry of mass 2000 kg slows from 20 m/s to 5 m/s in 10 s. What is the change in momentum of the lorry?
