a car traveling at + 7.0 m/s accelerates at a rate of + 0.80 m/s^2 for an interval of 2.0 s. Find the VF

Given:

The formula of VF is v=u+at

Coressponding to:

v = final velocity

u = initial velocity which is 7m per second

a = acceleration which is 0.08m per second^2

t = time which is 2.0 seconds

Substitute:

y=u+a

y=7 + (0.80*2)

7+1.6=8.6

VF=8.6 m/second^2

To solve this type of problem, the formula for linear-motion and acceleration will be used. The formula is stated below:

Vf = Vi + at

Where:

Vf = final velocity

Vi = initial velocity

a = acceleration

t = time

Substituting the given values into the equation:

Vf = 7 m/s + (0.8./s^2) * (2 s)

Vf = 8.6 m/s
