A150-if object takes 1.5 minutes to travel s 2,500-meter straight path. it begins the trip traveling 120 m/s and decelerates to a velocity of 20 m/s. what was it's acceleration?

When an object moves in uniform circular motion, the direction of its acceleration is a) in the same direction as its velocity vector. b) in the opposite direction of its velocity vector c) is directed toward the center of its circular path. d) is directed away from the center of its circular path. e) depends on the speed of the object.
