ma= mg –N
N=m(g-a) =
=m (g- v²/R) =
= 34.1{9.8 - (4.23²/9.15 )}=
=267 N.

ma=N-mg
N= m(g+a) =

A 34.1 kg child rides a Ferris wheel whose diameter is 18.3 m. When the ride is turning at a constant rate, the child’s speed has a constant value of 4.23 m/s. Find the normal force the seat exerts on the child at:
a) The top of the ride
b) The bottom of the ride
here are answers, don't know what steps were taken to get this though, like formulas, just need a walk through
a. 267N
b. 401N
