Q1. A music fan at a swimming pool is listening to a radio on a diving platform. The radio is constant frequency when this fellow clutching his radio, jumps off.

a) Describe a person left behind on the platform

b) A person down below floating on a rubber raft.

Q2. A flat (unbanked) curve on a highway has a radius of 300.0 m. A car rounds the curve at a speed of 44.0 m/s.

a)What is the minimum coefficient of friction that will prevent sliding?

Know the answer is .659 I have solved this part.

b) Assume the highway is icy and the coefficient of friction between the tires and pavement is only one-third what you find in part (a). What should be the highest speed of the car so it can round the curve safely?
