During an auto accident, the vehicle's air bags deploy and slow down the passengers more gently than if they had hit the windshield or steering wheel. According to safety standards, the bags produce a maximum acceleration of 60g, but lasting for only 40 ms (or less). How far does a person travel in coming to a complete stop in 40 ms at a constant acceleration of 60g? (Express your answer in meters.)

A VW Beetle goes from 0 to 42.0 mi/h with an acceleration of +2.35 m/s2. (a) How much time does it take for the Beetle to reach this speed? (b) A top-fuel dragster can go from 0 to 42.0 mi/h in 0.750 s. Find the acceleration (in m/s2) of the dragster.

A student drops an object out the window of the top floor of a high-rise dormitory. (a) Neglecting air resistance, how fast is the object traveling when it strikes the ground at the end of 3.9 s? First used standard British units and then express the speed in mi/h for a familiar comparison. (ft/s and mi/h) (b) How far, in meters, does the object fall during the 3.9 s? Comment on how many floors the dormitory probably has. (Assume that there are 32 floors/100 m.)

I need help solving this question. A rocket starting from rest rises vertically and accelerates at a constant rate of 13 m/s2 for 7 min. At this point the engine of the rocket accidently fails and completely shuts down. (Neglect air resistance and any variation in the acceleration due to gravity) a) What is the speed of the rocket when the engine shuts down? b) How high is the rocket above the ground at the point where the engine shuts down? c) How much higher will the rocket rise after the engine fails? d) What is the total time of the rocket in air? e) What is the average speed of the rocket for the entire trip?
