PRACTICE ANOTHER

At the end of a race a runner decelerates from a velocity of9.50m/s at a rate of1.50m/s².

(a)

How far in meters does she travel in the next7.20s? (Assume the deceleration of1.50m/s²is constant over the full7.20s.)

m

(b)

What is her final velocity in m/s?

m/s

(c)

Evaluate the result. Does it make sense?
