Is it cost money to ask? A rope is tied to a tree limb and
A rope is tied to a tree limb and is used by a swimmer to swing into the water. The person starts from rest with the rope held in the horizontal position, as shown in the figure on the power point file attached, swings downward and then let go of the rope. His initial height is h0 = 415 m and final height is hf = 105 m. If the force due to air resistance is neglected,What is the total work done on the person by the tensional force of the rope?If the speed of the swimmer is measured to be 67.8 m/s, and the mass of the swimmer is 75.0 kg, find the total work done on the swimmer by the frictional force – air resistance during this swinging process. … read more
