Does a free falling object fall 2 meters in twice the time as it falls 1 meter? Why? a. Yes, it takes twice as long to fall twice as far. b. Yes, it takes longer to fall farther. c. No, since it is speeding up as it falls it will cover the same distance in a shorter time. d. No, it takes the same time since it does not accelerate.

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?
