Question

y A 2 kg ball moving to the right along the x-axis at 5.0 m/s collides with a stationary 4.0 kg ball After the collision, the 2 kg ball is seen moving at 370 above the x-axis and the 4 kg ball is moving at 60° below the x-axis as shown below in the diagram. a) Find the speed of the each ball after the collision. b) Is this collision elastic or inelastic? Explain your answer with appropriate computations. y- 5 m's 37 60° 2 kg 4 kg 4 kg

Answer 1

Concept:- we use momentum conservation for motion in two dimension to find the speed and then find initial and final kinetic energies to verify the type of collision - elastic or inelastic, ***************************************************************************************************
