If a ball is given an acceleration of 3.0 meters/second while be pushed with a force of 0.75 Newton’s, what is the mass of the ball?

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.

The act of moving from one place to another. a. locomotor b. aerobic c. stationary d. static
