acceleration of the car.

9) A skater goes from a standstill to a speed of 5.7 m/s in 10 seconds. What is the
acceleration of the skater?

10) As a shuttle bus comes to a normal stop, it slows from 9.9 m/s to 0.0 m/s in 5 s. Find the
average acceleration of the bus.

11) During a race, a sprinter increases from 5.0 m/s to 7.5 m/s over a period of 1.25s. What
is the sprinter's average acceleration during this period?

12) A baby sitter pushing a stroller starts from rest and accelerates at a rate of 0.6 m/s. What
