Time: 50 minutes; Calculators & formulae provided at the end = only aid; ask no questions!
1) [5] A 2.0 kg parcel is launched up a ramp which ends in a horizontal surface with known
initial speed 3.5 m/s. The ramp makes a 30-degree angle with the horizontal and is 2.5 m
long. The coeﬃcient of kinetic friction between parcel and ramp is given as 0.2. Calculate the
velocity vector of the parcel as it arrives at the top of the ramp (it will launch into the air
at this point!). Begin your solution with a complete free-body diagram for the parcel on the
ramp.

2) [5] A 3.0 kg parcel arrives at the top of a ramp which makes a 45-degree angle with the
horizontal with a speed of 2.4 m/s. It lands some distance daway on the horizontal surface.
Calculate this distance while neglecting air drag. Do not use a (memorized) formula for the
range, but derive your result for dfrom the kinematic equations given in the formula sheet.
Provide a free-body diagram for the parcel while it is airborne.
