Question

**Please show the 2nd part of this**

Part 1: A spring with a constant of 1550 N/m is compressed 5.00 cm at the bottom of a frictionless ramp at angle of 10.0 degrees. How far up the ramp will a 0.750 kg mass travel, from this compressed distance? (looks like '1.34 m') Answer: 1.52 m

Part 2: If, in reality, the previous block only went up 0.800 m, what is the coefficient of kinetic friction? (looks like '0.123')

Answer 1
