A bicycle is rolling down a circular portion of a path; this portion of the path has a radius of 9.30 m. As the drawing illustrates, the angular displacement of the bicycle is 1.130 rad.

a vehicle slows from 14 m/s west to 2.0 m/s west in 2.86 seconds. what is the acceleration of the vehicle in m/s/s?

Emily holds a banana of mass m over the edge of a bridge of height h. She drops the banana and it falls to the river below. Use conservation of energy to find the speed of the banana just before hitting the water.

While watching ocean waves at the dock of the bay, Otis notices that 10 waves pass beneath him in 30 seconds. he also notices that the crests of successive waves exactly coincide with the posts that are 5 meters apart.

Your body is presently converting chemical potential energy from food into thermal energy at a rate of about 100 J/s, or 100 W. If heat were flowing out of you at a rate of about 200 W, would your body temperature go up or down?
