I am sitting in a car, which is undergoing acceleration in the forward direction of magnitude a. I feel a force pushing me horizontally backwards, into the back of the car seat. If my mass is M and the acceleration due to gravity is g, what is the magnitude of this force ?
Options:
Answer:
C
Solution:
In the car's frame I am at rest, so the backward push I feel is a pseudo-force of magnitude (equivalently, the seat pushes me forward with so that I accelerate at ). The magnitude is .
