1.	A particle of mass m, initially at rest is acted upon by a variable force F for a brief interval of time T. It begins to move with a velocity u after the force stops acting. F is shown in the graph as a function of time. The curve is a semicircle. Then
Answer» `u=(piF_(0)^(2))/(2m)` `u=(piT^(2))/(8M)` `u=(piF_(0)T)/(4m)` `u=(piF_(0)T)/(2m)` SOLUTION :IMPULSE = Area of SEMI circle
