A 60 kg person rides in a 20 kg cart
moving at 13 m/s at the bottom of a valley that is in the shape of an arc of a circle
with a radius of 36 m. What is the apparent weight of the person as the cart passes
the bottom of the valley?
F_centripital = m*v^2/r
F = ma
The Attempt at a Solution
So this seems a little too easy to be correct.
Apparent weight = m(a+g)=m(v^2/r+g)
The thing I am wondering about is the sign on gravity according to it being in the bottom of a valley.
Is my work correct?
