Problem

A car of mass

1.2\times10^{3}\,\text{kg}

and a truck of mass

1.0\times10^{4}\,\text{kg}

are each to be accelerated uniformly from rest to

15\,\text{m\,s}^{-1}

10\,\text{s}

. a. (a) Determine the common acceleration produced. b. (b) Calculate the average force that must act on the car. c. (c) Calculate the average force that must act on the truck and hence find the ratio of the force on the truck to that on the car.
