An ultimate Frisbee player (body mass of 54 kg) sprints at 7.1 m/s and makes a quick turn to her right. In the stance phase during this turn, her vertical acceleration is 5.0 m/s2 and her horizontal deceleration is -2.0 m/s2. If the static coefficient of friction between her foot and the turf is 0.8, how small of a radius (m) can she have on her turn not to slip? Assume that air resistance is negligible.

The 190.3-lb cabinet is subjected to the force F = 24.3(t + 1) Ib where t is in seconds. If the cabinet is initially moving to the left with a velocity of 19 ft/s, determine its speed whent = 5.5 s. Neglect the size of the rollers. 30°
After seeing a giant rock rolls into the highway, the driver slams on the brake and steers the truck onto an emergency escape ramp. The angle between the ramp and the horizontal is 0 = 15.0', and the magnitude of the velocity i of the truck is 30.0 m/s right after entering the ramp. If the coefficient of kinetic friction µk (for the ramp) is 0.720, then how far along the ramp does the truck travel until it stops? *Use work-energy theorem to answer this question and assumed that the wheels of the truck are locked (not rolling). *Include a free body diagram to solve this problem.
Shoes made for the sports of boulderingand rock climbing are designed to provide a great deal of frictionbetween the foot and the surface of the ground.

In the back of the truck is a 200kg box that has a coefficient of static friction of 0.8 and a coefficient of kinetic friction of 0.4 between the truck and the box. You are driving on the freeway at 25m/s. There is a car ahead of you that is driving at 30m/s. Your front bumper is 30m behind the back of the first car. You would like to pass the other car and pull back into the same lane when your back bumper is 10m ahead of the front bumper of the first car in 5 seconds. The length of the car ahead of you is 3m and the length of your car is 4m.a) What minimum acceleration do you need to do this?b) What distance does your car travel in that time?c) Does the box in your truck start to slide off the truck?
