Applied Mechanics and Graphic Statics A ball of mass 1 kg moving with a velocity of 2 m/sec collides a stationary ball of mass 2 kg and comes to rest after impact. The velocity of the second ball after impact will be 1.0 m/sec Zero 2.0 m/sec 0.5 m/sec 1.0 m/sec Zero 2.0 m/sec 0.5 m/sec ANSWER DOWNLOAD EXAMIANS APP
Applied Mechanics and Graphic Statics Ball ‘A’ of mass 250 g moving on a smooth horizontal table with a velocity of 10 m/s hits an identical stationary ball ‘B’ on the table. If the impact is perfectly elastic, the velocity of the ball ‘B’ just after impact would be 5 m/sec Zero 10 m/sec None of these 5 m/sec Zero 10 m/sec None of these ANSWER DOWNLOAD EXAMIANS APP
Applied Mechanics and Graphic Statics A body A of mass 6.6 kg which is lying on a horizontal platform 4.5 m from its edge is connected to the end of a light string whose other end is supporting a body of mass 3.2 kg as shown in below figure. If the friction between the platform and the body A is 1/3, the acceleration is 1.25 m/sec² 0.75 m/sec² 0.5 m/sec² 1.00 m/sec² 1.25 m/sec² 0.75 m/sec² 0.5 m/sec² 1.00 m/sec² ANSWER DOWNLOAD EXAMIANS APP
