Conservation Of Momentum (ht Only) (GCSE Physics)

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

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?

A bullet (0.01 kg, 500 m/s) passes through a block of 2 kg and emerges at 100 m/s. What speed does the block recoil at?

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 small mass collides elastically with identical stationary mass in one dimension. Which outcome is correct?

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 0.2 kg puck moving east at 6.0 m/s collides elastically with a 0.2 kg puck at rest and rebounds west at 2.0 m/s. What was the speed of the struck puck immediately after collision?

Two ice skaters push off each other. Skater A of mass 50 kg moves at 1.2 m/s and Skater B moves the opposite way at 0.80 m/s. What is the ratio of their momenta magnitudes pA:pB?

Two-dimensional collision: particle A (1 kg) with velocity (3 i + 0 j) m/s collides with B (2 kg) at rest. After collision A has velocity (1 i + 2 j) m/s. What is B’s velocity?

A car of mass 1200 kg and speed 20 m/s hits a stationary truck of mass 2400 kg and they lock together. What is their speed after impact?

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?
