A block with mass m=5kg is placed at position A and given an initial velocity Va=2m/s Down a frictionless circular ramp. Between positions B and C it travels over a flat rough surface having a coefficient of kinetic friction Mk=.25. Finally it travels over a flat frictionless surface and contacts am uncompressed so spring with spring constant k=1250N/m. The block comresses the spring at distance Delta (X) and comes to rest at position D.
2. Relevant equations
A) beginning at position A use conservation of energy to calculate the blocks velocity when it reaches position B
B) begimning at position B use conservation of energy to calculate the block’s velocity when it reaches position C . Don’t forget friction!!!!
C) beginning at position C use conservation of energy to calculate the distance Delta(X) that the spring is compressed when the block reaches position D
D) starting over at position A use conservation of energy directly between positions A and D and show that you get the same distance Delta(X) as part c) without having to calculate the velocities at position B and C
3.Please I’m super lost and have tried everything can someone solve and show me?!!!
