A bicycle has an average speed of 7.00 km/h. How far will it travel in 5.0 seconds?

In the below image, at what point are the kinetic energy and potential energy of the pendulum bob equal?

Consider a ball that increases in speed by 3 m/s each second as it rolls from rest down an inclined plane. If the ball takes 4 seconds to reach the bottom, what will be its speed at the bottom?

Kinetic energy can be measured in terms of       i) work done on an object to put it into in motion.   ii) work done on a moving object to bring it to rest.
