A typical running track is an oval with 74-m-diameter half circles at each end. A runner going once around the track covers a distance of 400 m . Suppose a runner, moving at a constant speed, goes once around the track in 1 min 40 sWhat is her centripetal acceleration during the turn at each end of the track?

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

what is the actual question though?
