Can someone help me with these questions:

Question 1:

6. Consider a concrete block that is being lowered vertically. If the mass of the block is M and is constantly nimrinf,l downward with an acceleration of 53, (a) Draw the free body diagram to indicate all the forces acting on the block. (b) Calculate the net force acting on the block. (c) Calculate the work done on the block, if the block is being lowered by a distance d. 7. A block of mass 50 kg is set into motion up an inclined plane with an initial speed of vi = 8.00 m/s. The block comes to rest after traveling d =15.00 m along the plane, which is inclined at an angle of 0 = 30.08 to the horizontal. For this motion, determine (20 pts) (a) The change in the block's kinetic energy (b) The change in the potential energy of the block (c) The friction force exerted on the block. (d) What is the coefficient of kinetic friction
