Applied Mechanics and Graphic Statics A shell travelling with a horizontal velocity of 100 m/sec explodes and splits into two parts, one of mass 10 kg and the other of 15 kg. The 15 kg mass drops vertically downward with initial velocity of 100 m/sec and the 10 kg mass begins to travel at an angle to the horizontal of tan”1 x, where x is 43926 43894 43954 43895 43926 43894 43954 43895 ANSWER DOWNLOAD EXAMIANS APP
