Work is done when an external force of 10 x 10^3 N push a body weighing 30 x 10^3 N from a floor up an incline plane. The distance travelled is 40 m. The total height gained is 10 m. At this point, the work done is converted into potential energy and kinetic energy. If the surface is frictionless, determine the change of kinetic energy

Use the information presented in the graph to answer the questions. which segments show acceleration? which segment indicates that the object is slowing down? what is the velocity of segment b? what is the acceleration of segment b?

Astone is dropped from a cliff and falls 9.44 meters. what is the speed of the stone when it reaches the ground? a. 13.6 m/sec b. 1.39 m/sec c. 185 m/sec d. 9.80 m/sec

A1-lb collar is attached to a spring and slides without friction along a circular rod in a vertical plane. the spring has an undeformed length of 5 in. and a constant k =25 lb/ft. knowing that the collar is released from being held at a determine, the speed of the collar and the normal force between the collar and the rod as the collar passes through b.
