Calculate the magnitude of the acceleration of a sled that is heading down a 39° slope (one that makes an angle of 39° with the horizontal). the coefficient of kinetic friction on ice is μk = 0.100. (take the x direction to be parallel to and down the slope and the y direction to be perpendicular to the slope.)

a= 5.41 m/s²

Explanation:

For this problems  (where an object is sliding down a slope with friction)

acceleration a = g * (sinΘ - µ*cosΘ)

so

a = 9.8m/s² * (sin39º - 0.100*cos39º)

a= 5.41 m/s²
