A 200g steel ball A hangs on a 1.0m long string. The ball A ispulled sideways so that the string is at a 45 degree angle, thenreleased. At the very bottom of its swing the ball strikers a 1000gsteel paperweight B that is resting on a frictionless table.

a. what is the speed the ball A just before the impact theblock?
b.what is the speed VA and VB after collison?

c.what is rebounding angle θ3?
