A water-skier is being pulled by a tow rope attached to a boat. As the driver pushes the throttle forward, the skier accelerates. A 67.8-kg water-skier has an initial speed of 5.3 m/s. Later, the speed increases to 11.7 m/s. Determine the work done by the net external force acting on the skier. W = IN
An asteroid is moving along a straight line. A force acts along the displacement of the asteroid and slows it down. The asteroid has a mass of 3.4x 104 kg, and the force causes its speed to change from 7000 to 4700m/s. (a) What is the work done by the force? (b) If the asteroid slows down over a distance of 1.4x 106 m determine the magnitude of the force. (a) Work= (b) F= i IN i
A 5690-kg satellite is in a circular earth orbit that has a radius of 3.14 x 107 m. A net external force must act on the satellite to make it change to a circular orbit that has a radius of 8.29 × 106 m. What work must the net external force do? Note that the work determined here is not the work Wlift done by the satellite's engines to change the orbit. Instead, the work Wis W = Wlift + Wgravitational, where Wgravitational is the work done by the gravitational force. Number Units
