Problem

A force of

10\,\text{N}

acts for

2\,\text{s}

on two trolleys that start from rest on a frictionless track. Trolley P has a mass of

1\,\text{kg}

and trolley Q has a mass of

2\,\text{kg}

. a. (a) Calculate the acceleration produced in each trolley. b. (b) Determine the change in velocity of each trolley at the end of the

2\,\text{s}

. c. (c) Which trolley undergoes the greater change in velocity?
