The spring shown in the figure is compressed 80.0 cm and is used to launch a 82kg. physics student along a frictionless track, Given values are K= 85000 Nm and Height = 11m. Now consider the track as frictionless until it starts up the 32degree incline, and then friction kicks in. a) If the student only makes it 45.0m up the incline, how much work was done by friction? b) What was the coefficient of friction on the ramp?

Question

The spring shown in the figure is compressed 80.0 cm and is used to launch a 82kg. physics student along a frictionless track, Given values are K= 85000 Nm and Height = 11m.

Now consider the track as frictionless until it starts up the 32degree incline, and then friction kicks in.

a) If the student only makes it 45.0m up the incline, how much work was done by friction?

b) What was the coefficient of friction on the ramp?
