A 0.17 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 → = ( 17.3 - 2.67 t 2 ) i ̂ , with F → 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 = 0.464 s and t = 2.17 s? (b) What is the change in momentum of the puck between t = 0 and the instant at which F = 0?

A stationary 2.17-kg object is struck by a stick. The object experiences a horizontal force given by F = at - bt 2, where t is the time in seconds from the instant the stick first contacts the object.
