Earth that are large enough to be detected by radar (the figure below shows space debris in orbit tracked
by radar), but there are far greater numbers of very
small objects, such as flakes of paint. Calculate the
magnitude of the force exerted by a 0.150 mg chip of
paint that strikes a spacecraft window at a relative
speed of 4.00 x 103 m/s, given the collision lasts
5.40 x 10-8 s. (Assume the paint chip sticks to the
spacecraft.)
Calculate the magnitude of the force exerted by the
paint chip.

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?
