Captain john stapp is often referred to as the "fastest man on earth." in the late 1940s and early 1950s, stapp ran the u. s. air force's aero med lab, pioneering research into the accelerations which humans could tolerate and the types of physiological effects which would result. after several runs with a 185-pound dummy named oscar eightball, captain stapp decided that tests should be conducted upon humans. demonstrating his valor and commitment to the cause, stapp volunteered to be the main subject of subsequent testing. manning the rocket sled on the famed gee whiz track, stapp tested acceleration and deceleration rates in both the forward-sitting and backward-sitting positions. he would accelerate to aircraft speeds along the 1200-foot track and abruptly decelerate under the influence of a hydraulic braking system. on one of his most intense runs, his sled decelerated from 282 m/s (632 mi/hr) to a stop at -201 m/s/s. determine the stopping distance and the stopping time.

Aspecial electronic sensor is embedded in the seat of a car that takes riders around a circular loop-the-loop ride at an amusement park. the sensor measures the magnitude of the normal force that the seat exerts on a rider. the loop-the-loop ride is in the vertical plane and its radius is 23 m. sitting on the seat before the ride starts, a rider is level and stationary, and the electronic sensor reads 740 n. at the top of the loop, the rider is upside down and moving, and the sensor reads 370 n. what is the speed of the rider at the top of the loop?

As part of your daily workout, you lie on your back and push with your feet against a platform attached to two stiff springs arranged side by side so that they are parallel to each other. when you push the platform, you compress the springs. you do an amount of work of 79.0 j when you compress the springs a distance of 0.230 m from their uncompressed length. (a) what magnitude of force must you apply to hold the platform in this position? (b)how much additional work must you do to move the platform a distance 0.230 m farther? (c) what maximum force must you apply to move the platform a distance 0.230 m farther?
