Find the change in momentum of an 1,580 kg car that increases its speed from 8 m/s to 19.4 m/s while traveling in the same direction.

An 1,102 kg car increases its speed from 7.2 m/s to 19.4 m/s in a time of 23.6 s while traveling in the same direction. What minimum force, applied in the direction of motion, is needed to do this? Give your answer in Newtons.

A 270 g ball has a kinetic energy 85.4 J. What is the magnitude of its momentum? Give your answers in kg m/s.
