block is resting on a ramp as shown in the figure below. You can change the inclination angle θ by raising one end of the ramp. The block has a mass mb=6.5 kg. At the interface between the ramp and the block, the coefficient of static friction is μs=0.4, and the coefficient of kinetic friction is μk=0.28. I managed to calculate that: slip angle is θ= 21.8 degrees acceleration is 1.09 m/s^2. I am trying to find: Let the angle θ be the angle you calculated , θslip (21.8 degrees) . To keep the block from slipping, you apply a horizontal (parallel to the surface of Earth) force directed to the right on the block. Your horizontal force F→Yb has a magnitude of 45 N. Calculate
Problem:
A block is resting on a ramp as shown in the figure below. You can change the inclination angle θ by raising one end of the ramp. The block has a mass mb=6.5 kg.

slip angle is θ= 21.8 degrees
acceleration is 1.09 m/s^2.

Let the angle θ be the angle you calculated , θslip (21.8 degrees) . To keep the block from slipping, you apply a horizontal (parallel to the surface of Earth) force directed to the right on the block. Your horizontal force F→Yb has a magnitude of 45 N. Calculate the magnitude and direction of the force due to static friction for this new situation, assuming that the block does not slip. Enter a magnitude for this part, but consider what the sign of your answer tells you about the direction of the force.
