A 65.5 kg person jumps from rest off a 2.83 m-high tower straight down into the water. Neglect air resistance during the descent. She comes to rest 1.15 m under the surface of the water. Determine the magnitude of the average force that the water exerts on the diver. This force is nonconservative.

Refer to Interactive Solution 6.59 for a review of the approach taken in problems such as this one. A 53.0-kg person jumps from rest off a 4.40-m-high tower straight down into the water. Neglect air resistance during the descent. She comes to rest 1.40 m under the surface of the water. Determine the magnitude of the average force that the water exerts on the diver. This force is non-conservative.

A 950-kg race car can drive around an unbanked turn at a maximum speed of 44 m/s without slipping. The turn has a radius of 140 m. Air flowing over the car's wing exerts a downward-pointing force (called the downforce) of 12000 N on the car. (a) What is the coefficient of static friction between the track and the car's tires? (b) What would be the maximum speed if no downforce acted on the car? Refer to Interactive Solution 6.59...

21. A person jumps off a diving board 5.0 m above the water's surface into a deep pool. The person's downward motion stops 2.2 m below the surface of the water. Calculate the speed of the diver just before striking the water, in m/s (ignore air friction).

(3) A professional diver jumps (up) off of a cliff that is 18 m high. Draw a sketch of the cliff, defining your origin and final position. (Careful with negative and positive signs.) Unlike the WB ssignment, assume the diver jumps up first and has an initial vertical velocity is 2.5 m/s. (Ignore air resistance.) (a) How long does it take the diver to hit the water? (b) How high from the top of the cliff does the diver reach...

Starting from rest, a 68.0 kg woman jumps down to the floor from a height of 0.790 m, and immediately jumps back up into the air. While she is in contact with the ground during the time interval 0 < t < 0.800 s, the force she exerts on the floor can be modeled using the function F = 9,200t − 11,500t2 where F is in newtons and t is in seconds. (a) What impulse (in N · s) did...
