Aski starts from rest and slides down a 24° incline 95 m long. part a
if the coefficient of friction is 0.085, what is the ski's speed at the base of the incline?
express your answer using two significant figures.
part b
if the snow is level at the foot of the incline and has the same coefficient of friction, how far will the ski travel along the level? use energy methods.
express your answer using two significant figures.

here we know that ball will drop down by total distance 3.2 m

so here we know that

now using kinematics

now in the same time it will cover horizontal distance of 0.75 m

so speed of the ball will be

a displacement distance is size of displ

i had this question and the answer was 3.15 miles.
