good evening I have a difficult request for you. would you kindly show me how to solve this problem using the conversation of energy approach and the approach with Newton's laws i would like to see the comparison. also please so all your steps and algebraic manipulation my maths isn't so good so I struggle to understand if there are steps involved algebra missing.
I know this question has been answered before,but the answer vary so much I'm not sure which is correct.
I hope this isn't too difficult a request?
thank you in advance.
26. Review. As shown in Fig- Cure P8.26, a light string that does not stretch changes from horizon- tal to vertical as it passes over the edge of a table. The string connects m₁, a 3.50-kg block originally at rest on the horizontal table at a height h = 1.20 m above the floor, to mo, a hanging 1.90-kg block orig- Figure P8.26 inally a distance d = 0.900 m above the floor. Neither the surface of the table nor its edge exerts a force of kinetic fric- tion. The blocks start to move from rest. The sliding block m, is projected horizontally after reaching the edge of the table. The hanging block m, stops without bouncing when it strikes the floor. Consider the two blocks plus the Earth as the system. (a) Find the speed at which m, leaves the edge of the table. (b) Find the impact speed of m, on the floor. (c) What is the shortest length of the string so that m1 m₂ d h
