Conservation Of Momentum (ht Only) (GCSE Physics)

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?

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

Two ice skaters initially at rest push off symmetrically and move at ±2.5 m/s. If left skater mass 60 kg, what is right skater mass?

An isolated system has total momentum zero. Two identical masses are moving directly towards each other. If one has speed 6 m/s, what is the other’s speed?

A bullet of mass 0.010 kg strikes and embeds in a block of mass 2.0 kg at rest. Bullet speed was 400 m/s. What momentum does the block+bullet have immediately after impact?

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 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?

In two-dimensional elastic collisions, conservation applies to which quantities?

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?

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

A 1.0 kg ball strikes a 4.0 kg block initially at rest; after perfectly inelastic collision they move together at 0.6 m/s. What was ball speed before collision?
