Disc P is projected straight towards disc Q. If all consequent collisions are perfectly elastic, predict the final motion of the three discs. C B A D 2 / 5 2) The diagram shows the masses and velocities of two trolleys about to collide. After the impact they move off together. What is the total kinetic energy of the trolleys after the collision? 12 J 1.3 J 19 J 18 J 3 / 5 3) The diagram shows a cannon ball fired from cannon. The mass of the cannon is 1000 kg and the mass of the cannon ball is 10 kg. The recoil velocity of the cannon is 5.0 m s–1 horizontally. What is the horizontal velocity of the cannon ball? 200 m s–1 5000 m s–1 500 m s–1 2000 m s–1 4 / 5 4) A body, initially at rest, explodes into two masses M1 and M2 that move apart with speeds v1and v2 respectively. What is the ratio v1/v2? (M2/M1)½ M2/M1 M1/M2 (M1/M2)½ 5 / 5 5) What is the magnitude of the momentum of an oil tanker of mass 50,000 tonnes travelling with a speed of 50 m s-1? 2.5 × 107 kg m s-1 2.5 × 108 kg m s-1 2.5 × 109 kg m s-1 2.5 × 106 kg m s-1 Your score is Restart quiz
