A winch is used to pull a small boat up a slipway

A winch is used to pull a small boat up a slipway as shown in the figure below. The boat has a mass of 15 tonnes and is accelerated to the top of the slope, from a stationary start, to a velocity of 1.2 m/s in 45 s. The slope is 22 to the horizontal and the coefficient of friction between the slipway and the boat can be taken as 0.3. Winch 22" Draw a free body diagram for the boat and include with dotted lines, the components of the weight of the boat along and perpendicular to the incline. a. b. Determine the tractive effort of the winch.
