A car is traveling up a hill that is inclined at an angle θ above the horizontal. Determine the ratio of the magnitude of the normal force to the weight of the car when (a)  θ = 16oand (b)  θ = 38o.

An incline is tilted at an angle of 6.7° above the horizontal. A box of mass 34 kg is pushed up the incline with a force F along the incline. If the acceleration of the box is 1.1 m-s2, calculate the magnitude of F (in N) that is needed.

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 0.410. (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? (a) Number i Units (b) Number Units

Find the tension in each cable supporting the 700-N cat burglar. (Assume the angle ? of the inclined cable is 38.0°.) (A) inclined cable,(B) horizontal cable, (C) vertical cable
