Regina is starting a sprint. she presses against the right starting block with 540 N at 135 deg. clockwise from the right horizontal. She presses against the left block with 390 N at 158 deg. clockwise from the right horizontal. what is the net horizontal force (from both legs)? What is the net vertical force? Resultant force? What is the normal force between the right foot and the track surface? What can she do to improve her horizontal force?
