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?

1. study the scenario. the particles in some system are moving around quickly. a few minutes later, the particles are moving, on average, more slowly. how does this change in motion affect the temperature of the system? the temperature of the system did not change. the speed of the particles does not affect temperature, the number of particles affects the temperature.the temperature of the system is lower now than it was initially. faster moving particles result in a higher temperature for the system.the temperature of the system is higher now than it was initially. slower moving particles result in a higher temperature for the system.the temperature of the system did not change. the speed of the particles has no effect on the temperature, only the type of atom affects the temperature.
