Applied Mechanics and Graphic Statics Pick up the correct statement from the following. A rubber ball when strikes a wall rebounds but a lead ball of same mass and velocity when strikes the same wall, falls down None of these Change in momentum suffered by lead ball is less that of rubber ball Momentum of rubber ball is less than that of lead ball Rubber and lead balls undergo equal changes in momentum None of these Change in momentum suffered by lead ball is less that of rubber ball Momentum of rubber ball is less than that of lead ball Rubber and lead balls undergo equal changes in momentum ANSWER DOWNLOAD EXAMIANS APP
Applied Mechanics and Graphic Statics A shell of mass 100 kg travelling with a velocity of 10 m/sec breaks into two equal pieces during an explosion which provides an extra kinetic energy of 20000 Joules. If the pieces continue to move in the same direction as before, then the speed of the faster one must be 40 m/sec 50 m/sec 30 m/sec 20 m/sec 40 m/sec 50 m/sec 30 m/sec 20 m/sec ANSWER DOWNLOAD EXAMIANS APP
