... A trained sea lion slides from rest with constant acceleration down a 3.0-mlong ramp into a pool of water. If the ramp is inclined at an angle of 23 above the horizontal and the coefficient of kinetic friction between the sea lion and the ramp is 0.26, how long does it take for the sea lion to make ...

The result is that even though the momenta of the individual objects changes, p for the system is zero. The momentum that one mass gains, the other loses ...

... answer: We’ll use Fnet t = p. Since the ball changes direction, p = m v = m (vf - v0) = 1.3 [22 - (-13)] = (1.3 kg) (35 m/s) = 45.5 kg · m /s. Thus, t = 45.5 / 1200 = 0.0379 s, which is just under 40 ms. During this contact time the ball compresses substantially and then decompresses. This happen ...
