Question

1 Abody of mass 5*10 kg moving with speed 2 ms 'collides with a body of mass 15x103
kg inelastically and sticks to it. Then, loss in kinetic energy of the system will be
A) 7.5 kJ B) 15kJ C )10kJ D) 5 kJ​

Answer 1

Answer:15kj

Explanation:

Conserve momentum toh get velocity of both the bodies as v=0.5 m/s .

And then find change in kinetic energy
