The rocket sled shown in the figure decelerates at a rate of 155 m/s2 . Its passenger has a mass of 75 kg. Use a coordinate system in which the sled is moving in the positive direction, and assume the contact forces with the seat are the only forces acting on the passenger. (a) Calculate the horizontal component of the force that the seat exerts against his body, in newtons. What is the ratio of the magnitude of the horizontal force to the magnitude of the force of gravity?

Question
The rocket sled shown in the figure decelerates at a rate of 155 m/s2 . Its passenger has a mass of 75 kg. Use a coordinate system in which the sled is moving in the positive direction, and assume the contact forces with the seat are the only forces acting on the passenger.
(a) Calculate the horizontal component of the force that the seat exerts against his body, in newtons.
What is the ratio of the magnitude of the horizontal force to the magnitude of the force of gravity?
Find the angle of the total force that the seat exerts against his body. Give your answer in degrees from the negative horizontal direction, with positive being clockwise.
