Static friction should be m*a*u, right?
So 274 for the back and 245 for the front? But what we really need to know is the coefficient of friction on the bus.

So that's how much she weighs.
F = μ*m*g Front seat: 0.50*(40 kg +10kg)*g = 25*g Back seat: 0.70*(40 kg)*g = 28*g She should take the back seat. |
