Question

2 Seamus and Aoife are walking back from Bonnie's place, when they come across a tree that has fallen across the road. Being the kind-hearted people they are, they decide to try to move this tree out of the way. This tree has a mass of 2400 kg, so this wl be no small task a What is the weight of the tree, in Newtons? b With a team of passersby, Seamus and Aoife hook a chain around the tree so that the chain makes an angle of 37° with the ground at the point of attachment to the fallen tree. Draw a free body diagram of this situation. c If 3/4 of the tree's weight can be supported by the chain, then the tree will start sliding. If each person can pull with a force of 50 N, how many people are needed to get the tree sliding with this rope arrangement? d Instead, by setting up series of pulleys, they attach the chain to the back of a tow truck that can supply the right amount of force. The truck starts pulling, and the tree just starts to slide at a constant speed. What is the net force on the tree?
