When you throw a ball, the work you do to accelerate it equals the kinetic energy the ball gains. If you do twice as much work when throwing the ball, does it go twice as fast?
a) Yes. Twice as much work will give the ball twice as much kinetic energy. Since KE is proportional to the speed, the speed will double as well. b) Yes. Twice as much work will give the ball four times as much kinetic energy. Since KE is proportional to the speed squared, the speed will be the square root of 4, or twice as fast. c) No. Twice as much work will give the ball twice as much kinetic energy. But since KE is proportional to the speed squared, the speed will be ?2 times larger. d) No. Twice as much work will give the ball four times as much kinetic energy. Since KE is proportional to the speed, the speed will be four times larger.

Let's say that you are spinning a fixed-frequency buzzer attached to a string in a circular path around you at a constant speed. The frequency that you hear as you spin the buzzer sity?
1.is greater than the frequency of the buzzer and it is constant. 2.alternates between being greater than the frequency of the buzzer and less than the frequency of the buzzer. 3.is less than the frequency of the buzzer and it is constant. 4.is the same as the frequency of the buzzer.
