Principle of Impulse and momentum
... The 250 N crate is acted upon by a force having a variable magnitude P = 100t, where t is in seconds. Determine the crate’s velocity 2 s after P has been applied. The initial velocity is v1 = 1 m/s down the plane, and mk = 0.3. ...

... have to use the momentum formalism, rather than F=ma. It is also the first example of non-uniform acceleration that we will deal with using the Force Approach. On the mathematical side, it gives us more experience with differential equations than we get from simple UAM (uniformly accelerated motion) ...
