Awater balloon launcher uses an elastic band with a spring constant of 115 n/m. to use the launcher, you stretch the band back with a balloon in 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 the balloon forward. what is the kinetic energy of the balloon when it reaches the natural length of the band? explain how you found the answer.
d. what is the speed of the balloon when it reaches the natural length of the band?
