Problem

A crate of mass

20\,\text{kg}

is pulled along a horizontal floor by two workers. The first worker exerts a force of

50\,\text{N}

and the second worker exerts

30\,\text{N}

, both in the same direction. A frictional force of

10\,\text{N}

opposes the motion. (i) Find the net force acting on the crate. (ii) Determine the acceleration produced.
