A 945-kg car traveling rightward at 22.6 m/s slams on the brakes and skids to a stop (with locked wheels). If the coefficient of friction between tires and road is 0.972, determine the distance required to stop. PSYW

A hockey puck (mass = 2 kg) leaves the players stick with a speed of 20 m/s and slides on the ice before coming to rest.The coefficient of friction between the puck and the ice is 0.9. How far will the puck slide after leaving the players stick? m

A 620 kg car pulling a 495 kg trailer accelerates forward at a rate of 2.20 m/s2. Assume frictional forces on the trailer are negligible. Ignore air drag.   (c) What is the force (in N) exerted by the trailer on the car?   Magnitude: Direction: (forward or backward)

Block A (mass ma) rests on a tabletop. It is connected by a horizontal cord passing over a light, frictionless pulley to a hanging block B (mass mg). The kinetic friction between Block A and the tabletop is f. The block are released from rest. Which of the followings is the correct Free Body Diagram of block B? mag mag mag mag B B B a a mal mg mg Fig. A Fig. B Fig. C Fig. D Fig. E Figure B Figure E Figure A Figure C Figure D

An object with a mass of 4kg lies on a rough plane inclined at 20 degrees to horizontal. A force of 35N is applied parallel and up the plane. The object accelerates at 2.5m/s^2. What is the Uk between the object and plane

ents Once I went skiing. I was at the bottom of a snow ramp with a speed of 14.0 m/s. Assuming that the coefficient of friction between the snow and the skis was 0.2 determine my speed at the top of the ramp. The angle theta with the horizontal was 25°. The rise of the snow ramp was h=3.5 meters high. h Skier Met < Previous OL 1

A 9.61kg box on a ramp with an incline of 26.36° slips, giving it an acceleration of 0.31m/s2. What is the coefficient of kinetic friction between the box and the ramp?

At Ted's request, Bill pushes the pizza box across the granite countertop towards Ted. When the box leaves Bill's hand it is sliding at 2.60 m/s. The box comes to rest over a distance of 110 cm. What is the coefficient of kinetic friction, uk, between the pizza box and the countertop? (Ignore air drag.)
