how much work is required to lift a 10 newton weight from 4.0 meters to 40.0 meters above the surface of earth

A runner completes one full lap around a 400 meter track. What is her displacement?

A ball is tossed vertically upward from a height of 2 m with an initial velocity of 10 m/s. Just before the ball hits the ground, its velocity will be what?

A runner moving at a velocity of 6 m/s increases the velocity in a 2 s time interval to a rate of 10 m/s. What is the rate of acceleration?

A ball rolling across a field with an acceleration of -0.5 m/s rolls 12.5 m and then comes to a stop after 8 seconds. What was the ball's initial speed?

How much force must be produced by the biceps brachia at a perpendicular distance of 3 cm from the axis of rotation at the elbow to support a weight of 200 N at a perpendicular distance of 25 cm from the elbow?

A block weighing 17 N oscillates at one end of a vertical spring for which k = 120 N/m; the other end of the spring is attached to a ceiling. At a certain instant the spring is stretched 0.24 m beyond its relaxed length (the length when no object is attac...
