A racecar travels northward on a straight, level track at a constant speed, traveling 0.550 kilometer in 40.0 seconds. The return trip over the same track is made in 45.0 seconds. (a) What is the average velocity of the car in meters per second for the first leg of the run

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

the maxium height is 34m/s
