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 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 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?

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

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 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 projectile of mass 0.50 kg moving at 20 m/s lodges in a stationary wooden block of 4.5 kg. What fraction of initial kinetic energy is lost?

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 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?
