Pls help me answer number 3 letter A and B with complete solution #1. In Figure 1, a 5.0 kg block is sent sliding up a plane inclined at e = 37° while a horizontal force F ofmagnitude 75 N acts on it. The coefficient of kinetic friction between block and plane is 0.30. What are the(a) magnitude and (b) direction (up or down the plane) of the block's acceleration? The block's initialspeed is 4.0 m/s. (c) How far up the plane does the block go? (d) When it reaches its highest point, doesit remain at rest or slide back down the plane?#2. A uniform board is leaning against a smooth vertical wall. The board is at an angle above thehorizontal ground. The coefficient of static friction between the ground and the lower end of the board is0.550. Find the smallest value for the angle such that the lower end of the board does not slide along theground.# 3. A physics professor is pushed up a ramp inclined upward at 30.0° above the horizontal as he sits inhis desk chair that slides on frictionless rollers. The combined mass of the professor and chair is 85.0 kg.He is pushed 3.50 m along the incline by a group of students who together exert a constant horizontalforce of 600 N. The professor's speed at the bottom of the ramp is 2.00 m/s.A) What is the work done by the 600N force?B) What is the work done by gravity?C) What is the work done by the normal force?D) Use the work-energy theorem to find his speed at the top of the ramp.#4. A 1.5-kg block of wood floats on water with 68 percent of its volume submerged. A lead block isplaced on the wood, fully submerging the wood to a depth where the lead remains entirely out of thewater. Find the mass of the lead block.
