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

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 = 02.0 – 3.00t2)i, with F in Newton’s 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 = 0.500 s and t = 1.25 s?
(b) What is the change in momentum of the puck between t = 0 and the instant at which F = 0?
