A shell is fired from a cannon with a velocity v at an angle θ with the horizontal direction. At the highest point in its path, it explodes into two equal pieces, one retraces its path to the cannon and the speed of the other piece immediately after the explosion is :
A
3 υ cos θ
B
2 υ cos θ
C
υ cos θ
D
υ cos θ
Text Solution
Verified by ExpertsThe correct answer is:
A
P 1 = P f
mV cos θ = 
(–V cos θ + 
V ′ )
V ′ = 3V cos θ
