Exercise -3- A golf player must make a goal of length 1 = 6.0 m so his ball, of mass m = 45 g, reaches the hole. The player hits the ball an initial velocity of value vo. The ball, considered as a material point, material moves with a rectilinear motion. During its motion, it is subjected to a constant frictional force of value 4.0 x 10-² N. 1- Name the forces acting on the ball and represent them on a diagram. 2- Give the expression of the work of each of these forces during the motion. 3- Is the mechanical energy of the ball remains the same during the motion? Justify your answer. 4- What must be the value of v, for the ball to reach the hole with a velocity of zero?
