Asnowmobile has a mass of 2.5x10^2 kg. it is acted upon by a force so that its velocity changes from 6.0 m/s to 28 m/s. what is the change in momentum show your work?

The motor m applies a time-varying force of f (200 t) n, where t is in seconds. box b with mass 200 kg starts from rest, and the coefficients of kinetic and static friction are 0.2 and us 0.3 the acceleration due to gravity is g 9.8 m/s2 b 300 a) find the time ' when the box starts to move. b) calculate the speed of the crate at 3 s c) calculate the power delivered by the motor at t 3 s
