A 3.7-kg block is pushed 3.3 m up a vertical wall with constant speed by a constant force of magnitude F applied at an angle of 0 = 30° with the horizontal, as shown in the figure below. If the coefficient of kinetic friction between block and wall is 0.30, determine the following. (a) the work done by F (b) the work done by the force of gravity (c) the work done by the normal force between block and wall (d) By how much does the gravitational potential energy increase during the block's motion?

A force |F| = 30 N is applied to the object with mass m = 2 kg. The angle theta = 25 degree. The object starts from rest and moves by displacement d = 2  m.  The coefficient of kinetic friction between the object and the floor is 0.2.  In this problem use g = 10m/s^2. The weight of the object is  W = mg. Find the work done on the object by the force F.  i hace calucated F = 54.37 From the above question, find the magnitude of the normal force between the object and the floor. Answer in Newton.   I have calculated magnutide of normal force = 32.67   From the above question, Find the work done on the object by friction. Watch out for the sign. I calculated  work done by friction = -13.06 QUESTION: From the above figure, find the final kinetic energy of the object. Answer in Joule.
