Question

A 0.25 kg puck is initially stationary on an ice surface with negligible friction. At time t = 0, a horizontal force begins to move the puck. The force is given by F= (10.6 - 3.52t^2) , with in newtons and t in seconds, and it acts until its magnitude is zero. (a) What is the magnitude of the impulse on the puck from the force between t = 0.407 s and t = 1.04 s? (b) What is the change in momentum of the puck between t = 0 and the instant at which F = 0?
