A small glider is placed against a compressed spring at the bottom of an air track that slopes upward at an angle of 34.0° above the horizontal. The glider has mass 5.00 x 10⁻2 kg. The spring has 620 N/m and negligible mass. When the spring is released, the glider travels a maximum distance of 1.70 m along the air track before sliding back down. Before reaching this maximum distance, the glider loses contact with the spring.

a) The gravitational force on the glider
b) The normal force exerted by the track on the glider
c) The tension force in the spring
d) The frictional force between the glider and the track
