A uniform ladder of length L and weight w is leaning against a vertical wall. The coefficient of static friction between the ladder and the floor is the same as that between the ladder and the wall. If this coefficient of static friction is u, = 0.385, determine the smallest angle the ladder can make with the floor without slipping. 52.4 Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation. Carry out all intermediate results to at least four-digit accuracy to minimize roundoff error.°
USE GRESA METHOD FOR THE SOLUTION 3. A 1.50 x 103 kg car, whose front is facing to the right (towards +x-axis) and whose engine is turned off and in neutral, is held at rest on a frictionless ramp using a cable whose one end is attached to the car's front at an angle 27.0° with respect to the ramp's surface. The other end of the cable is attached to a wall perpendicular to the horizontal and the ramp is raised 30.0° above the horizontal. (Note: A free-body diagram (FBD) is required in this problem) (a) Find the force exerted by the ramp on the car's wheels. (b) Find the tension on the cable. (c) Suppose the wall where the other end of the cable was attached was replaced by a rotating motor. If the car is now accelerating towards the peak of the ramp at 3.00 m/s2 due to the rotating motor, how much tension is being exerted by the cable on the car?

Required information NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. Bucket A and block C are connected by a cable that passes over drum B. Drum B rotates slowly counterclockwise and the coefficients of friction at all surfaces are μ = 0.35 and μ = 0.25. Given: W= 120 kg. m B W 30° Determine the smallest combined mass m of the bucket and its contents for which block C will remain at rest. The smallest combined mass m of the bucket and its contents for which block C will remain at rest is 28.896 kg.
