At launch the space shuttle weighs 4.5 million pounds. when it is launched from rest, it takes 8.00 s to reach 162km/h , and at the end of the first 1.00 min its speed is 1620km/h .
a)
assuming
the acceleration is constant during each time interval (but not
necessarily the same in both intervals), what distance does the shuttle
travel during the interval from 8.00 s to 1.00 min?

Write the equation for momentum, first using symbols for the variables, then using words for the variables.

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?
