Explanation / Answer
the downward force of gravity Fgrav = mg m= mass of the passenger g =acceleration due to gravity net forceacting on the passenger Fnet = m a acceleration a = velocity / time Fgrav + Fnormal = Fnet Fnormal = F net - Fgrav since normal forceis equal to apparent weight plug the values and get theanswere
