In a uniform circular motion, the acceleration is perpendicular to the velocity at every instant. Is this true when the motion is not uniform-that is, when the speed is not constant?
A 0.525 ball starts from rest and rolls down a hill with uniform acceleration, traveling 146 during the second 10.0 of its motion. How far did it roll during the first 4.00 of motion?
A ball starts from from rest and rolls down a hill with uniform acceleration, traveling 150 m during the second 5.0 s of its motion. How far did it roll during the first 5.0 s of motion?
