A Sunset student, whose mass is 60 kg, is standing at
the top of a 50 meter hill on a snowy day. The student
slips on some ice and slides to the bus stop, which is a
vertical drop of 8 meters. (a) What is the student's
speed when they reach the bus stop at the bottom of
the hill? (b) Draw what an ENERGY PIE CHART (like the
skate park) would look like at 4 meters down the hill.

Orque can be calculated by multiplying the force (n) applied at 90? to the lever arm at a distance (m) from the pivot point (point of rotation), the compound si unit for the torque is n? m. if the force (at 90? to the lever arm) applied is 15 n and it is applied at 2.0 m from the pivot point (point of rotation), what is the torque on the lever?
