Answer:
Explanation:
Given
mass of body A
mass of body
Velocity before Collision is
after collision
let and velocity of B after collision in x and y direction
conserving momentum in x direction
as thus
Conserving momentum in Y direction
thus velocity of B after collision is
(b)Change in total Kinetic Energy
Initial Kinetic Energy of A And B
Total initial Kinetic Energy =1250 J
Final Kinetic Energy of A And B
Final Kinetic Energy
Change
