Question 7 (1 point) A skier slides down a frictionless hill with an acceleration of 2.04 m/sz. What angle does the hill make with the horizontal? Question 8 (1 point) A shoe sits on a ramp without moving. As the angle of the ramp is increased, the shoe starts to move. This is because: O A) force of gravity on the shoe has increased 0 B] the component of the normal force along the ramp has increased O C) the coefficient of static friction has decreased 0 D) the normal force has increased O E) the component of gravity acting along the plane of the ramp has increased Question 9 (1 point) According to Newton's third law, when you walk across a floor, the force that propels you fomrard is O the force of tension of your feet on the floor 0 the force acting on you working against gravity O the force applied by your feet on the floor 0 the force of the floor applied against your feet
