Challenge Problems (Problem 99)

A 120-kg astronaut is riding in a rocket sled that is sliding along an inclined plane. The sled has a horizontal component of acceleration of $5.0\text{m}\text{/}{\text{s}}^2$ and a downward component of $3.8\text{m}\text{/}{\text{s}}^2$. Calculate the magnitude of the force on the rider by the sled. (Hint: Remember that gravitational acceleration must be considered.)
