I can't seem to get past this one, and it should be possible to solve without using integration. Any help would be great :D(adsbygoogle = window.adsbygoogle || []).push({});

A 0.25 kg object is stationary on a frictionless surface. At t = 0, a horizontal force begins to move the object. The force is given by F = (12 - 3t^2) and acts until its magnitude is zero.

a) What is the magnitude of the impulse between t = 0.5 and t = 1.25 s?

b) What is the change in momentum from when the object is stationary to when the magnitude of the force is zero?
