A rocket-driven sled running on a straight, level track is used to investigate the physiological effects of rapid accelerations on humans. One such sled can attain a velocity of 1600 km/h in 1.8 s, starting from rest.
(a) Assuming that the acceleration is uniform, what is its value in m/s[square] ?(b) Express the acceleration in (a) in terms of g, where g = 9.8 m/s[square].(c) Under the last 2.00 km of the track there is a trough of water. The “brakes” of the rocket consist of a scoop that displaces water from the trough, stopping the sled. Assuming that the sled stops at the end of the trough, what is the deceleration of the sled, expressed in terms of g?
