Problem
A student pulls a trolley along a horizontal laboratory floor by applying a force of 60N at an angle of 25∘ above the horizontal.
(i) Calculate the horizontal and vertical components of the applied force.
(ii) The trolley moves 10m horizontally in 5s. Find the work done by the horizontal component of the force during this motion, assuming the vertical displacement is negligible.
(iii) Determine the average power delivered by the student over this interval.
