A 6250-kg satellite is in a circular earth orbit that has a radius of 2.43 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 7.48 × 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 W is W = Wlift + Wgravitational, where Wgravitational is the work done by the gravitational force. Number i Save for Later Units Attempts: 0 of 3 used Submit Answer

Pulling a cube of weight (356N) a distance (610cm) on flat ground with a constant launch after applying a force that makes an angle (30°) with the horizon. If the coefficient of friction between the cube and the ground is (0.25), find the work done by the frictional force e 12:34
A 45.9-kg box is being pushed a distance of 6.54 m across the floor by a force P whose magnitude is 168 N. The force P is parallel to the displacement of the box. The coefficient of kinetic friction is 0.208. Determine the work done on the box by (a) the applied force, (b) the friction force, (c) the normal force, and (d) by the force of gravity. Be sure to include the proper plus or minus sign for the work done by each force.

An engine can pull a train with a force of 2.95 × 10* N. It pulls 20 railcars each of mass 2.00×10' kg. The railcars are subject to rolling friction equal to 0.5% of their weight. (a) What is the work done by the engine on the train (not including the engine) when it starts from rest and moves 1.00 km? (b) What is the speed at 1.00 km?
An archer using a simple bow exerts a force of 189 N to draw back the bow string 0.49 m. (Assume the given force is the force exerted at the very end of the pull.) (a) What is the total work (in J) done by the archer in preparing to launch her arrow? (Hint: Compute the total work as: total work = 1 2 [Ffinal − Finitial]d.) J (b) If all the work is converted into the kinetic energy of the arrow upon its release, what is the arrow's speed (in m/s) as it leaves the bow? Assume the mass of the arrow is 0.021 kg and ignore any kinetic energy in the bow as it relaxes to its original shape. m/s (c) If the arrow is shot straight up, what is the maximum height (in m) achieved by the arrow? Ignore any effects due to air resistance in making your assessment. (Assume the arrow is initially 2 m from the ground.) m
