PRACTICE ANOTHER

At the end of a race a runner decelerates from a velocity of 9.50 m/s at a rate of 1.50 m/s².

(a)

How far in meters does she travel in the next 7.20 s? (Assume the deceleration of 1.50 m/s² is constant over the full 7.20 s.)

m

(b)

What is her final velocity in m/s?

m/s

(c)

Evaluate the result. Does it make sense?
