Problem

A warehouse winch pulls a crate along a smooth horizontal floor with a constant horizontal force of

300\,\text{N}

. The winch motor supplies a steady power of

1.5\,\text{kW}

. a. (a) Calculate the maximum constant speed the crate can attain. b. (b) At this speed, the crate is required to cover a distance of

60\,\text{m}

. Determine the time taken to travel this distance. c. (c) Immediately after completing the

60\,\text{m}

journey, the motor is switched off and a frictional force of

150\,\text{N}

opposes the motion. If the mass of the crate is

100\,\text{kg}

, calculate the additional distance the crate will slide before coming to rest.
