a cyclist traveling at an initial speed of 10.0 m/2. She accelerates at a rate of 0.5 m/s^2. What is her final velocity after 9.0 s?
negative acceleration
equal to the force pulling the car down hill
Peter's speed is decreasing
acceleration
run a constant stream of water down the slide
18.7 m/s north
unbalanced forces
14.5 m/s
