A 75kg snowboarder has an initial velocity of 5.0 m/s at the top of a 28°
incline. After sliding down the 110m long incline (on
which the coefficient of kinetic
friction is μk=0.18), the snowboarder has attained a velocity v.
The snowboarder then slides
along a flat surface (on which μk=0.15) and comes to a rest after a
distance x.
a. Use energy calculations to determine x.
b. Use Newton’s 2nd Law to find the snowboarder’s acceleration
while on the...
