6 Small parcels are being loaded onto a trolley. Initially the parcels are 2.5 m above the trolley.
- A parcel is released from rest and falls vertically onto the trolley. Calculate
(a) the time taken for a parcel to fall onto the trolley,
(b) the speed of a parcel when it strikes the trolley.

Parcels are often damaged when loaded in the way described, so a ramp is constructed down which parcels can slide onto the trolley. The ramp makes an angle of \(60 ^ { \circ }\) to the vertical, and the coefficient of friction between the ramp and a parcel is 0.2 . A parcel of mass 2 kg is released from rest at the top of the ramp (see diagram). Calculate the speed of the parcel after sliding down the ramp.
