Homework Help: Physics

Posted by Sandhu on Wednesday, October 21, 2009 at 6:52pm.

A 12.0 kg shell is launched at an angle of 55 degrees above the horizon with an initial velocity of 150 m/s. When at its highest point, the shell explodes into 2 fragments - 1 fragments is 3 times heavier than the other. The 2 fragments reach the ground at the same time, ignore air resistance. If the heavier fragment lands back at the same point from which the shell was launched, where will the 2nd fragment land and how much energy was released by the explosion?
