It was once recorded that a Corvette left skid marks that were 38 m in length. Assuming that the Corvette skidded to a stop with a constant acceleration of 19 m/s 2from the brakes due to friction, determine the starting speed of the Corvette before it began to skid.

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.

An object moves from position +34m to the position -15m in 15 seconds. what is the total displacement? what is the total velocity?

When a bicycle coasts uphill, it moves slower and slower as it climbs. why? a. its kinetic energy is transforming into heat energy. b. its potential energy is transforming into kinetic energy. c. its kinetic energy is transforming into potential energy and heat energy. d. its potential energy is transforming into kinetic energy and heat energy.
