A 2000-kg automobile starts from rest at point A on a 6° incline and coasts through a distance of 150 m to point B. Knowing that slipping is impending during the period and neglecting air resistance and rolling resistance, determine the speed of the automobile at point B in m/s. (Use concept of work and energy in solving) 150 m 20 m A B c

A robot arm moves in the vertical plane so that the 0.14-kg cylinder P travels in a circle about point B, which is not moving. Know that arm BP starts from rest in a horizontal position and that the speed of Pincreases at a constant rate of 200 mm/s². 0.8 m Draw the free-body diagram of the cylinder P that is required to determine the force acting on the cylinder. (You must provide an answer before moving on to the next part.) 0.8 m P 1 I
