Your adorable middle school self is pulling your rolling backpack on the way to first period. Since this is the days before chromebooks, your backpack is heavy (mass 22 kg), and the coefficient of friction between the wheels and the ground is 0.32. If you can pull with a force of 125 N at an angle of 35, and you are 25 meters from your class, answer the following questions a) Draw a free body diagram for your backpack b) Which forces (if any) do positive work? c) Which forces (if any) do negative work? d) Which forces (if any) do NO work? e) Find the amount of work done by each of the above forces Find the net work done on the backpack g) if you started from rest, how fast are you and the backpack moving after the 25 meters? 2.0 m 0.15 kg 0.60 m 0.50 m A block of mass 0.15 kg is placed at point A at a height 2.0 m above the bottom of a track, as shown in the figure above, and is released from rest. It slides with negligible friction down the track, around the inside of the loop of radius 0.60 m, and leaves the track at point C at a height 0.50 m above the bottom of the track. (a) Calculate the speed of the block when it leaves the track at point C. (b) Draw a Free Body Diagram for the block when it is at the top of the loop at point B. (c)Calculate the minimum speed the block can have at point B without losing contact with the track. (d) Calculate the minimum height above the bottom of the track at which the block can be released and still go around the loop without losing contact with the track.
