A) 7.5 J
B) 5 J
C) 2.5 J
D) 10 J
Correct Answer: A
Solution :
This is a case of inelastic collision, in which momentum is conserved, and total energy. Let\[{{u}_{1}}\]be velocity of body of mass 5 kg, and\[{{u}_{2}}\]of 2.5 kg. Then Momentum before collision = Momentum after collisionYou need to login to perform this action.
