Conservation Of Momentum (ht Only) (GCSE Physics)

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

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 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 closed system initially at rest explodes into two fragments of masses 3 kg and 2 kg. If the 3 kg fragment has speed 5 m/s to the right, what is the 2 kg fragment’s speed and direction?

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?

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?

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?

A system of two gliders on frictionless track: mass 2 kg at 1 m/s collides elastically with 3 kg at rest. After collision, 2 kg is at -0.2 m/s. What is speed of 3 kg?

A 3.0 kg object moving at 4.0 m/s collides elastically with a 2.0 kg object at rest. Which statement is true immediately after collision?

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?
