Question1

Sam, who's mass is 70 kg, takes off across level snow in his jet powered skis. The skis have a thrust of 204 N and the coefficient of kinetic friction on snow of 0.1. Unfortunatately, the skis run out of fuel after only 12 s.

(a) what is Sam's top speed?

(b) How far has Sam travelled when he finally coasts to a stop?

Question2

A swimmer can swim in still water at a speed of 9.50 m/s. He intends to swim straight across a river that has a downstream current of 3.75 m/s.

A.)What have to the swimmer's direction been?

B.)What is his velocity relative to the bank?
