_ 3) The roller-coaster car of mass 1000kg reaches a vertical height of only 25 m on hill 2 before stopping. It traveled a total distance of 400 m. a)Determine the WMC and estimate the average friction force. b) What would be its velocity when it passes y=0 for the first time (after 250m) assuming same friction force 5 If mA=1 kg & m3 = 3 kg, and 9 = 300, a) what will be the speed of the blocks when the lower one has fallen 0.8 m? Assume ramp is frictionless. b) Repeat if m for the ramp is 0.29 Remember: distance moved for me, is not in the gravity direction. Suggest you use tilted axes & replace W, especially for (b) \"in
