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 4/5 3/5 5/3 3/4 4/5 3/5 5/3 3/4 ANSWER DOWNLOAD EXAMIANS APP
Applied Mechanics and Graphic Statics The velocity of a body fallen from height ‘h’, on reaching the ground is given by v = 1/√(2gh) v = 2gh² v = 2gh v = √(2gh) v = 1/√(2gh) v = 2gh² v = 2gh v = √(2gh) ANSWER DOWNLOAD EXAMIANS APP
