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.(a) u = πF02 / 2m(b) u = πT2 / 8m(c) u =πF0T / 4m(d) u = F0T / 2m
Answer» Correct answer is: (c) u =πF₀T / 4m
