(Answered) Given two identical 39 kg masses the first mass is moving

Academics

Given two identical 3.9 kg masses. The first mass is moving with a velocity v1 immediately before colliding with the second mass, which is suspended by a string of length 0.58 m The two masses are stuck together as a result of the collision. The compound system then swings to the right and rises to the horizontal level.The acceleration of gravity is 9.8 m/s 0.58m 3.9kg 7.8kg 3.9kgv 190? Find the kinetic energy of the compound system immediately after the collision.Answer in units of J.
