### Problem 1: Work and Energy on a Rough SurfaceA block slides on a rough horizontal surface from point A to point B. A force (magnitude \( P = 2.0 \, \text{N} \)) acts on the block between A and B, as shown in the diagram. Points A and B are 1.5 meters apart.#### Questions:1. **(a)** How much work is done on the block by the force \( P \)?2. **(b)** If the kinetic energies of the block at A and B are 6.0 J and 4.0 J, respectively, how much work is done on the block by the net force as the block moves from A to B?3. **(c)** What is the work done by the friction force?#### Diagram Explanation:The provided diagram illustrates the block and the force \( P \):- The block is positioned between points A and B.- A force \( P \) of 2.0 N is acting on the block at an angle of \( 40^{\circ} \) from the horizontal axis as the block moves from point A to point B.- The distance between points A and B is 1.5 meters.This problem requires the application of the work-energy principle and consideration of forces acting on the block. The work done by force \( P \), changes in kinetic energy, and work done by friction need to be determined from the given conditions.

True or False (No Explanation Needed) Work is also equal to the change in potential energy. Work done by gravity is always negative. An object at a higher point has larger potential energy than that of an object at a lower point. Friction affects the amount of energy an object has. Maximum work happens when the force is perpendicular to the direction of movement.

Consider an object of mass m = 4 kg on a frictionless table. The object experiences a repulsive force F = a/x2 + b/x, where F is in newtons and x is the position of the object relative to the origin. Write an expression for the work done by the repulsive force on the object as it moves from an initial position of x1 to a final position of x2. If the object starts at a position of x1 = 8.5 m apart, how much work, in joules, is required by an external force to bring it to a position of x2 = 2.5 m apart when a = 19 and b = 11? If the object starts at rest at a position x3 = 1.3 m and is released, at what speed v, in meters per second, will the object be moving when it is at position x4 = 12.5 m?
