A block with a mass of 10.09 kg is placed on a ramp. The ramp has an incline of ? = 25.7 degrees from the horizontal. The static coefficient of friction between the block and ramp is μs = 0.211, and the kinetic coefficient of friction between the block and ramp is μk = 0.112. A force, F, is exerted on the block as shown. Note that the force F is parallel with the ramp. What is the smallest value (magnitude) for the force, F, in Newtons that can be exerted on the block to hold the block stationary on the ramp? What is the largest value (magnitude) for the force, F, in Newtons that can be exerted on the block while still holding the block stationary on the ramp? What value (magnitude) for the force, F, is needed to move the block up the ramp at a constant speed?
A cord passes over a massless, frictionless pulley to connect an object with mass mA to an object with mass mB (the two objects are on opposite sides of the pulley). Find an expression for the tension in the cord. (Overall my answer was T=2mA mB g/mA+mB
This problem concerns the concept of tension in a rope. Consider a rope subjected to a pulling force on its two ends as shown in (Figure 1). The rope is stationary. An arbitrary point P divides the rope into a left-hand segment L and a right-hand segment R. Assume that segment R exerts a force of magnitude TTT on segment L. What is the magnitude FLRFLRF_LR of the force exerted on segment R by segment L? Give your answer in terms of T and other constants such as g. F_LR = ?

A block of mass M is suspended at rest by two strings attached to walls, as shown in the figure. The left string is horizontal with tension force T2 and and the right string with tension force T1 makes an angle θ with the horizontal. T1 is measured to be 24 N, and θ = 41.0°. What is the mass of the block, in kg? Use g = 10 m/s2. Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.
Instructions Use g = 10 m/s2 Always answer in standard units (SI units). Unless otherwise instructed. Answer to 2 decimal places. Unless otherwise instructed. A block of mass 3.0 kg is pushed up against a wall by force P that makes an angle of theta = 50 degree with the horizontal (see the figure). THe coefficient of static friction between the block and the wall is 0.25. Find the minimum force of P that can hold the block against the wall (the block does not accelerate downward).
