Question

Two balls, of masses mA = 45 g and mB = 70 g , are suspended. The lighter ball is pulled away to a 66∘ angle with the vertical and released.

Part A Determine the velocity of ball A before impact.

 

Part B Determine the velocity of ball A after the elastic collision.

 

Part C Determine the velocity of ball B after the elastic collision.

 

Part D Determine the maximum height of ball A after the elastic collision.

 

Comments

Please provide height of the string from which the two masses are suspended.
