Applied Mechanics and Graphic Statics A ball moving with a velocity of 5 m/sec impinges a fixed plane at an angle of 45° and its direction after impact is equally inclined to the line of impact. If the coefficient of restitution is 0.5, the velocity of the ball after impact will be 3.5 m/sec 2.5 m/sec 1.5 m/sec 0.5 m/sec 3.5 m/sec 2.5 m/sec 1.5 m/sec 0.5 m/sec ANSWER DOWNLOAD EXAMIANS APP
Applied Mechanics and Graphic Statics A stone was thrown vertically upwards from the ground with a velocity of 50 m/sec. After 5 seconds another stone was thrown vertically upwards from the same place. If both the stones strike the ground at the same time, then the velocity with which the second stone was thrown should be (Assume g = 10 m/sec²) 50 m/sec 25 m/sec 40 m/sec 15 m/sec 50 m/sec 25 m/sec 40 m/sec 15 m/sec ANSWER DOWNLOAD EXAMIANS APP
