8. Follow-up When the ferry leaves Guemes Island and heads back toward Anacortes, its speed increases from 0 to 5.8 m/s in 9.25 s. What
is its average acceleration?

The average acceleration of the ferry which leaves Guemes Island and heads back  toward Anacortes is 0.627m/s².

Given the data in the question;

To determine the average acceleration, we use the first equation of motion:

Where v is final speed, u is initial speed, a is acceleration and t is time taken.

We substitute our given values into the equation

Therefore, the average acceleration of the ferry which leaves Guemes Island and heads back  toward Anacortes is 0.627m/s².

0.63m/s²

Explanation:

The average acceleration can be derived from using the formula:

V = u + at

Where v = final velocity (m/s)

u = initial velocity (m/s)

a = acceleration (m/s²)

t = time (s)

V = u + at

V - u = at

a = v - u/t

a = ∆V/t

According to the provided information; v = 5.8m/s, u = 0m/s, t = 9.25s

a = ∆V/t

a = (5.8-0)/9.25

a = 5.8/9.25

a = 0.627

a = 0.63m/s²

Hence, the average acceleration is 0.63m/s²

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
