A Princeton prof. (mass = 70.0 kg), surprised by the large stopping force he calculates for jumping flat footed from a height of 0.12 m, decides to try the experiment. Calculate he deceleration (in g's) if he stops in a distance of 0.36 cm. (Do not try this. You could easily ...

Highway engineers often use quadratic functions to model safe stopping distances for cars like 1/2x quantity squared + 11/5x is used to model the safe stopping distance for car traveling at x miles per hour on dry, level pavement. If a driver can see only 200 feet ahead on a ...

A dragster accelerates from rest for a distance of 450m at 14 m/s^2. A parachute is then used to slow it down to a stop if the parachute gives the dragster an acceleration of -7m/s^2 how far has the dragster traveled before stopping?
