Assume that a passenger in a rollover accident must turn

through a radius of 3.0 m to remain in the seat of the vehicle.

Assume also that the vehicle makes a complete turn in

1 second.

a. Using the fact that the circumference of a circle is 2r,

what is the speed of the passenger?

b. What is the centripetal acceleration? How does it compare

to the acceleration due to gravity?

c. If the passenger has a mass of 60 kg, what is the centripetal

force required to produce this acceleration?

How does it compare to the passenger's weight?
