Changes In Momentum (physics Only) (GCSE Physics)

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 bus of mass 12 000 kg and a car of mass 1200 kg are moving at the same speed. Which has greater momentum?

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

A skateboarder (total mass 60 kg) moving at 6 m/s applies brakes that provide a constant backward force producing an impulse of -360 N·s. What is the skateboarder’s final speed?

A cyclist collides with a lamppost and comes to rest. Which quantity best measures the severity of the collision for the cyclist?

Two ice skaters push off each other. Before push both at rest; after push one skater of mass 50 kg moves at 1.2 m/s. What is the velocity of the other skater of mass 75 kg? (Conserve momentum)

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 cyclist of mass 70 kg moving at 5.0 m/s is brought to rest by an average braking force of 350 N. How long did the braking take?

Which scenario shows momentum is a vector quantity?

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)?

A truck of mass 3000 kg moving at 12 m/s collides head-on with another truck of mass 2000 kg moving at 8 m/s toward it. What is total momentum of the two-truck system before collision (take right as positive and assume second truck is moving left so negative)?
