- How much work is done against gravity to move an 800 kg weather monitor 300 km into the air? (re = 6.38 × 10® m, Me = 5.98 × 1024A student who weighs 553 N climbs a stairway (vertical height of 4.2 m) in 20 s. (a) How much work is done? J (b) What is the power output of the student? W3) The figure below illustrates a skier who is skiing on a large frictionless spherical ball of snow. The skier can be treated as a point-like object. The skier starts at the top of the ball with very little speed and picks up speed while traveling along the surface of the snow. During this time, the only forces acting on the skier are the gravitational force applied by the Earth and the normal force applied by the snow. At the moment the radial line extending from the skier to the center of the ball defines an angle a with respect to a vertical line, the skier is about to lose contact with the ball. Determine the value of a.
