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 density of a liquid could be found by using

Asmall object with mass 0.200 kg swings back and forth on the lower end of a light rope that is 3.00 m long. the upper end of the rope is attached to the ceiling. as the object swings through its lowest position, where the rope is vertical, the speed of the object is 5.80 m/s. at this point in the motion, what is the tension in the rope? (use g = 9.80 m/s2.)

What’s #16 asking and how do i solve it?
