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

Recall that the work WW done by a constant force F⃗ F→ at an angle θθ to the displacement Δr⃗ Δr→ is W=F⃗ ⋅Δr⃗ =FΔrcosθW=F→⋅Δr→=FΔrcos⁡θ. The vector magnitudes FF and ΔrΔr are always positive, so the sign of WW is determined entirely by the angle θθ between the force and the displacement. What is the work WnWn done on the box by the normal force? Express your answers in joules to two significant figures What is the work WTWT done by the tension force? Express your answers in joules to two significant figures.

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 4.6× 104 kg, and the force causes its speed to change from 7000 to 5800m/s. (a) What is the work done by the force? (b) If the asteroid slows down over a distance of 1.7× 106 m, determine the magnitude of the force.
