4. A body with an initial velocity of 8 m/s moves with a constant acceleration and travels 640m in 40 seconds. What is the acceleration of the body?

a= 9.81 s

Explanation:

vi= 8m/s

a= -9.81 m/s

d= 640m

t= 40s

1. Find final velocity

vf= vi +a(t)

vf= 8m/s + -9.81m/s x 40s

vf = -384.4 m/s

acceleration= change in velocity/ change in time

a= -384.4- 8= -392.4/ 40s = 9.81s

a= 9.81 m/s

Hopefully this helps and is correct! Much love ❤️

i think the answer would be reserve.

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
