Sheffield is famous for its snooker. A 170 g white ball is struck with a cue and travels along the snooker table at 12 ms-1. Calculate it's momentum.

3 / 10

Which of the following quantities has the same unit as the rate of change of momentum?

4 / 10

A 15 N force is applied to a 2.3 kg mass for 8 seconds. Calculate its initial momentum.

Trolley jousting. A Lidl Trolley TL of mass 21.0 kg, collides on a horizontal frictionless surface with an Aldi Trolley, TA of mass 22.5 kg. Before the collision TL was moving at 3.0 ms-1 and TA was at rest. They get stuck together, calculate their velocity.

Shoaib Akhtar is the fastest bowler ever. He throws a cricket ball of 163 g at a speed of 161.3km h-1 which strikes a stationary cricket bat. Calculate the momentum of the ball before the collision.

Physical Disability Rugby League (PDRL) is a format of rugby league for those with impairments. Anthony Seward (Warrington Wolves) has a mass of 70 kg and Sam Zeller (Leeds Rhinos) has a mass of 65 kg. Anthony is at rest and Sam runs towards him at a speed of 8 ms-1. They move together in the same direction, calculate at what speed.

A bullet of mass 4.02 g is fired at a speed of 940 ms-1 from an SA-80 rifle. The bullet strikes a block of hardwood of mass 0.512 kg hanging at rest from a long string. The bullet enters the wood and becomes lodged in the block. Calculate the initial speed the wooden block from rest immediately after impact.

A mini-cannon of mass 35.5 kg fires a turnip of mass 1.2 kg. If the turnip leaves the cannon at 214 ms-1 over 0.3 s, with what force does the mini-cannon recoil?

10 / 10

An Airbus A380 at maximum take-off weight, Amax = 575,000 kg, is taxing along at 37 km h-1. The pilot isn't paying attention and accidently hits head on another A380 that is completely empty taxing at 40 km h-1, Amin = 277,145 kg and they rebound off each other in opposite directions. If the collision reduces the speed of Amax to 6 ms-1 then what speed is Amin now travelling at?
