Calculate the maximum acceleration (in m/s2) of a car that is heading up a 13.5° slope (one that makes an angle of 13.5° with the horizontal) under the following road conditions. Assume that only half the weight of the car is supported by the two drive wheels and that the static coefficient of friction is involved--that is, the tires are not allowed to slip during the

Your answer is partially correct. A 60 kg crate is dragged across a floor by pulling on a rope attached to the crate and inclined 12° above the horizontal. (a) If the coefficient of static friction is 0.46, what minimum force magnitude is required from the rope to start the crate moving? (b) If Hk = 0.30, what is the magnitude of the initial acceleration (m/s^2) of the crate? %3D (a) Number i 276.52 Units (b) Number i 1.568 Units m/s^2

Suppose you have a stack of 17 identical steel bars (steel bars have a mass of 1.00kg each). You are required to pull out bar number 16 from the stack (counting from the top of the stack down). Assuming that your assistant holds all other bars in place.   If the coefficient of friction between steel and steel is 0.750, how hard do you have to pull (in N)?

An initially stationary box of sand is to be pulled across a floor by means of a cable in which the tension should not exceed 876 N. The coefficient of static friction between the box and the floor is 0.360. (a) What should be the angle between the cable and the horizontal in order to pull the greatest possible amount of sand, and (b) what is the weight of the sand and box in that situation?
