A) mg
B) 3.19 seconds
An ice skater is traveling in a straight, horizontal line on the ice with a velocity of v = 6.5 m/s in the positive x-direction. The coefficient of kinetic friction between the skates and the ice is μk = 0.23.
v = 6.5 m/s
μk = 0.23
A. Using the expression for normal force, write an expression for the skater's acceleration in the x-direction, a.
