Question A6
A car is initially travelling with a speed of 32 m-s¹ when it slows down with a constant accelera-
tion of magnitude 2.1 m-s-2.
If the tyres of the car have a radius of 35.0 cm, calculate the number of revolutions that each tyre
makes before the car comes to a stop. Assume that the car does not skid.

Problem 8
A carnival ride spins people in a circle to make them feel a centripetale
acceleration of 20 m/s². It spins the people around the circle at a speed
of 10 m/s. What must be the radius of the circle the people are spun
through? Don't forget units!
