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

|mv-mu| =πr^2/2
=π.r.r/2
=πF•T/2/2
mu=πF•T/4
