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 40 m/sec 15 m/sec 25 m/sec 50 m/sec 40 m/sec 15 m/sec 25 m/sec ANSWER DOWNLOAD EXAMIANS APP
