'please help me with this. A 1.666 kg block is held against a spring with spring constant of 188 N/m; which is compressed by 20.0 cm to the left, from the spring equilibrium position. When the block is released, it travels a horizontal distance of 2.0 m (from the spring equilibrium position), before it makes perfectly elastic collision with second block of mass 800 kg: The second block immediately enters & frictionless loop that has radius of 75.0 cm. If the coefficients of static and kinetic friction are 0.755 and 0.395 respectively along the straight path, does the block make it safely through the loop? If not; what is the minimum compression of the spring originally that will allow the block to make it safely through the loop? Your write up should include: Drawn Representation (sketch; FBD, motion diagram; labels; unknowns) Physics Representation (What are YOU trying to solve? Reword the question with proper physics terminology with units converted) Mathematical Representation (show equations, solve for unknowns) Layman Representation (Therefore statement including proper sig: figs. and units. Does this answer make physical sense? Why or why not?)'
