Question
A shell is fired from a canon with a velocity V at an angle q with the horizontal direction. At the highest point in its path, it explodes into two pieces of equal masses. One of the pieces come to rest. The speed of the other piece immediately after the explosion is
Options
A.3V cos θ
B.2V cos θ
C.3/2V cos θ
D.V cos θ
Solution
Vcom = V cosθ
V cos θ =
∴ v2 = 2V cos θ
