MY NOTES ASK YOUR TEACHER A skier speeds down a smooth ski slope which is at an angle of 0 = 220 with the horizontal. The mass of the skier is 67 kg. Take the downhill direction to be positive and uphill to be negative. (a) What net force (in N) is acting on the skier? (Indicate the direction with the sign of your answer.) (b) What is the acceleration (in m/s2) experienced by the skier? (Indicate the direction with the sign of your answer.) m/s2 (c) How does the net force experienced by the skier change if the ski slope becomes steeper? O increases decreases remains the same Supporting Materials Physical Constants Submit Answer 4. [-/1 Points] DETAILS MY NOTES ASK YOUR TEACHER The block in the figure below has a mass of 5.9 kg and it rests on an incline of angle 0. You then push on the block with a force of F = 35 N, directed up the slope as shown. Assume the incline is smooth and determine the angle of the incline if the block moves with constant speed
