b) A truck of total mass 18tonne descends a hill with a gradient of 1 in 14, i.e. a vertical movement of 1m for each 14m of movement along the slope. During this motion, the truck experiences a rolling resistance to its motion of 900N. Whilst travelling at a velocity of 54km/h, its brakes are applied, and the truck is brought uniformly to rest in a distance of 112m. During this period of constant deceleration, it may be assumed that the rolling resistance remains constant at 900N, this being in addition to the retarding force applied by the brakes. Calculate for the truck whilst it is slowing down: a) The vertical height through which it descends. b) Its decrease in potential energy. c) Its initial velocity in m/s. d) Its decrease in kinetic energy. e) The work done against the rolling resistance.

An industrial trolley of mass 300 kg is used to transport equipment and materials to a workstation within the R and D section. Initially the trolley is at the top of a 15 m high hill, which is inclined at 10º to horizontal as shown and travelling at 5 m/s before rolling down into the station. On reaching the bottom of the hill, brakes are applied to the trolley to slow it down to 0.25 m/s in 4.5 m. Determine: The braking force that slowed the trolley down The time it takes the trolley to slow down The deceleration of the trolley
