Using energy considerations, calculate the average force a 60.0-kg sprinter exerts backward on the track to accelerate from 2.00 to 8.00 m/s in a distance of 25.0 m, if he encounters a headwind that exerts an average force of 30.0 N against him.

A 50.0-kg student evaluates a weight loss program by calculating the number of times she would need to climb a 12.0-m high flight of steps in order to lose one pound (0.45 kg) of fat. Metabolizing 1.00 kg of fat can release 3.77 107 J of chemical energy and the body can convert about 20.0% of this into mechanical energy. (The rest goes into internal energy.) (a) How much mechanical energy can the body produce from 0.450 kg of fat? (b) How many trips up the flight of steps are required for the student to lose 0.450 kg of fat? Ignore the relatively small amount of energy required to return down the stairs.

A raindrop of mass 28.7 mg forms inside a cloud, and then starts to fall from a height of 707.1 m directly above a point P on the ground. As it falls, it is blown about by the wind and eventually hits the ground with a speed of 7.2 m/s a distance 471.5 m from point P. How much extra energy has it gained, or lost, during its journey to the ground? Enter the amount in Joules as a positive number if it gained energy, and a negative number if it lost energy.
