Which indicates what happens to the kinetic energy of an object when its speed increases? A)The kinetic energy does not change.

B)The kinetic energy increases by the same factor as the speed increase.

C)The kinetic energy increases by the square of the same factor as the speed increase.

D)The kinetic energy decreases by the same factor as the speed increase.

Awater balloon launcher uses an elastic band with a spring constant of 115 n/m to use thee launcher you stretch thee band back with a balloon n it the water balloons have a mass of 1.3 kg a) if you stretch the band by 0.8 m, what elastic force will the band exert? b) with the band stretched 0.8 m, how much elastic potential energy is stored in the spring? c) if you release the band, it pushes forward. what is the kinetic energy of the balloon when it reaches the natural length of the band? d) what is the speed of the balloon when it reaches the natural length of the band?
