A 0.35 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 = (12.2 - 3.10t2), 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 = 0.600 s and t = 1.20 s?b) What is the change in momentum of the puck between t = 0 and the instant at which F = 0?
