1. The problem statement, all variables and given/known data b) Calculate the maximum velocity of the empty carriage at D. (3 marks) 2. Relevant equations / 3. The attempt at a solution 750 x 9.8 = 7350 N No clue. Can't use SUVAT on the vertical plane to find time because v = u = 0 from peak/trough to peak/trough. Horizontal plane from C to D: s = ? u = ? v = ? a = 0 t = ? Maybe I could find u by finding v from B to C? Horizontal plane from B to C: s = ? u = 0 v = ? a = 0 t = ? Another dead end. Should I be using SUVAT at all?
