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

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+ay=7+(0.80*2)7+1.6=8.6 VF=8.6 m/second^2
