Divide by 2(pi) to put your answer in radians

use the equation hmg=mg + mv^2/r. for example my percentage was 35% and my radius was 30m. so .35(9.8)= v^2/30 and solve for v

use T= 2(pi)(r)/v to get the velocity and then use a= v^2/r to get part a

I got his top speed to be 10.76 m/s by using the frictional force in the equation. I just don't know which equation to use from there.

Homework Statement Joe, whose mass is 80kg, takes off across level snow in his jet powered skiis. The skiis have a thrust of 186N and a coefficient of kinetic friction on snow of 0.1. Unfortunately, the skiis run out of fuel after only 8 s. What is Joe's top speed? How far has Joe traveled...
