U6.1 – Momentum & 2D Collisions

A 20 N force is applied to a 450 g mass for 6 second and it moves 30 cm. Calculate the momentum of the mass.

The image above shows the before and after of a collision between two objects. Calculate the mass of object B.

A snooker player takes an aimed shot. The image above shows before and after the collision between the two snooker balls. Calculate the velocity of object C after the collision.

Alan the Alpaca, of mass 84 kg, sets off on a run. He picks up speed until he reaches 15 ms^-1 then Alan the Alpaca runs into a small child in a large hamster bowl, with a total mass of 32 kg. The force of the impact slows Alan the Alpaca to 9.3 ms^-1, and causes the small child in a large hamster ball to start moving. Calculate the velocity of the small child in a large hamster bowl immediately after the impact.

An Alpha particle collides head on with a stationary gold nucleus of mass 197u at a speed of 1x10⁶ ms^-1. This causes the gold nucleus to move at a speed of 1.31x10⁴ ms^-1. Calculate the speed of the Alpha-particle after the collision.

The image above shows the before and after of a collision between two objects. Calculate the mass of object H.

The image above shows the before and after of a collision between two objects. Calculate the velocity of object L before the collision.

If an object is stationary before impact, the final velocity of that object will be _____________.

The image above shows the before and after of a collision between two objects of the same mass. Calculate the at the angle to the horizontal which object Y moves off from after the collision.

Boccia is a target ball sport which tests both muscle control and accuracy. From a seated position, players propel balls, of mass 275 g, to land as close as possible to a white marker ball, known as the Jack. The diagram above shows a player using momentum to move their teams balls closer to the Jack through multiple collisions. Using the diagram above, calculate the mass of the Jack.
