3: A 10 kg box rests on a 30 degree incline and begins to slide down. (a) what is the acceleration if no friction is present? (b) What is the acceleration if the coefficient of kinetic friction is 0.20? (c) What is the final speed of the box when it reaches the bottom of an incline that is 200 m (use the answer in part b)

For problem 3 the input in EXCEL should be: Mass of the box, angle of incline( 0 to 90 degrees), coefficient of friction, Travel distance.
