Class XI Two billiard balls each of mass 0.05 kg moving in opposite directions with speed 6 m s−1s−1 collide and rebound with the same speed. What is the impulse imparted to each ball due to the other ? 0.5 kg m s−1 0.3 kg m s−1 0.6 kg m s−1 0.4 kg m s−1 A man of mass 70 kg stands on a weighing scale in a lift which is moving downwards with a uniform acceleration of 5 m s−2s−2 what would be the reading on the scale? 45 Kg 35 kg 53 kg 35 kg A train moving with a uniform speed of 54 kmph. What is its speed in m/s ? 15 m/s 1.5 m/s 9 m/s 90 m/s A batsman deflects a ball by an angle of 45∘∘ without changing its initial speed which is equal to 54 km/h. What is the impulse imparted to the ball? (Mass of the ball is 0.15 kg.) 4.6 kg m s−1 4.2 kg m s−1 4.4 kg m s−1 4.8 kg m s−1 A shell of mass 0.020 kg is fired by a gun of mass 100 kg.
