Question
The rocket sled shown in Figure 4.33 decelerates at a rate of $201 \textrm{ m/s}^2$. Its passenger has a mass of 75.0 kg. (a) Calculate the horizontal component of the force the seat exerts against his body. Compare this with his weight by using a ratio. (b) Calculate the direction and magnitude of the total force the seat exerts against his body. In this problem, the forces are exerted by the seat and restraining belts.
