Conservation Of Momentum (ht Only) (GCSE Physics)

A cart of mass 1.5 kg moving at 3.0 m/s collides inelastically with a 0.5 kg cart moving at -1.0 m/s (opposite). What is the velocity of the combined mass after sticking?

A ball bouncing elastically off a wall reverses its velocity from 6 m/s to -6 m/s in 0.02 s. What average force acted on a 0.3 kg ball?

A ball of mass m strikes a fixed wall. If momentum change magnitude is ?p, impulse J = ?p. Which statement about average force Favg if collision time doubles?

A car (mass 1500 kg) traveling at 20 m/s collides and sticks to a truck (mass 3000 kg) at rest. What fraction of initial momentum does the car retain after sticking?

A stationary 2.0 kg trolley is hit from behind by a 0.50 kg toy car moving at 3.0 m/s. After the collision the car and trolley stick together. What is their common speed immediately after the collision?

An astronaut in space (no external forces) throws a 2 kg tool at 4 m/s relative to the spaceship and recoils at 0.1 m/s. What is the astronaut+spaceship mass?

Two particles collide in 2D. The total momentum before collision is (6.0 i + 2.0 j) kg·m/s. After collision the x-component of momentum is 4.0 kg·m/s. What must be the y-component after the collision for momentum to be conserved?

A ball of mass m moving at u collides and sticks to mass 4m at rest. The final speed is u/5. Which conservation equation was used?

A perfectly elastic collision in one dimension conserves kinetic energy. For masses m and M (M>>m) with m moving, which is true after elastic collision?

A 0.4 kg ball moving at 8.0 m/s collides with a wall and reverses direction to -6.0 m/s. What change in momentum occurred?

An inelastic collision conserves momentum but not kinetic energy. Which of the following is a correct interpretation?
