A novice snowboarder who weighs 60kg is sliding down a 10 degree slope at a constant velocity of 8 m.s^-1.
When they reach the bottom of the slope, they slow down due to the kinetic friction between the snowboard and the snow.
Find the rate at which the skier is de accelerating once they are on the flat snow.
The Attempt at a Solution
I found the coefficient of kinetic friction (0.176), but how can you calculate the rate of de acceleration?
