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 5.5x 104 kg, and the force causes its speed to change from 7000 to 5500m/s. (a) What is the work done by the force? (b) If the asteroid slows down over a distance of 2.1x 106 m determine the magnitude of the force.

A constant 82.5-N force acts on a 6.54-kg box. The box initially is moving at 20.5 m/s in the direction of the force, and some time later the box is moving at 57.7 m/s. Determine the work (in J) done by this force. You may assume that only one force acts on the box.
A hummingbird is able to hover because, as the wings move downward, they exert a downward force on the air. Newton's third law tells us that the air exerts an equal and opposite force (upward) on the wings. The average of this force must be equal to the weight of the bird when it hovers. If the wings move through a distance of 2.9 cm with each stroke, and the wings beat 85 times per second, determine the work performed by the wings on the air in 1 m if the mass of the hummingbird is 3.2 g.
