(adsbygoogle = window.adsbygoogle || []).push({}); 1. A projectile of mass 50 kg moving horizontally at 100m/s explodes into three pieces. Two pieces fly off vertically while a third continues horizontally at 150m/s (neglect gravity).

What is the kinetic energy of the horizontally moving piece?

2. Relevant equations

KE=(1/2)mv^2

W=∆KE

W+KEi + PEi =KEf + PEf

PE=mgh

3. The attempt at a solution

W=∆KE

=(1/2)mvf^2-(1/2)mvi^2

But I got incorrect answer. The correct answer is 375000 J
