Transcribed Image Text:Your 160 lbm friend agrees to have his standing jump analyzed. Standing
on a force plate, he crouches to lower his center of gravity, then executes
a jump. The force plate measurement gives a reading that can be described
by the equation
(=)
F(t) = 480 sin
+ 160 (1 – t/t)
(10.27)
where F(f) is in lbf. Here the push-off duration z is 180 ms. How high will
your friend's center of gravity be elevated at the peak of his jump?

- You are working with a movie director and investigating a scene with a cowboy sliding off a tree limb and falling onto the saddle of a moving horse. The distance of the fall is several meters, and the calculation shows a high probability of injury to the cowboy from the stunt. Let's look at a simpler situation. Suppose the director asks you to have the cowboy step off a platform 2.55 m off the ground and land on his feet on the ground. The cowboy keeps his legs straight as he falls, but then bends at the knees as soon as he touches the ground. This allows the center of mass of his body to move through a distance of 0.670 m before his body comes to rest. (Center of mass will be formally defined in Linear Momentum and Collisions.) You assume this motion to be under constant acceleration of the center of mass of his body. To assess the degree of danger to the cowboy in this stunt, you wish to calculate the average force upward on his body from the ground, as a multiple of the cowboy's…arrow_forwardWhat is the power in kW produced by the La Rance tidal power station in France if the usable tidal range is 10 m?

- A lab assistant has suspended a spring from a door frame. When an object is attached to the spring's bottom end, the spring extends downward by an additional distance, d, measuring 4.80 cm.
