Question

a car traveling at +1.5 m/s accelerates at the rate of 0.65 m/s for an interval of 2.6a find vf

Answer 1

Vf ( final velocity) = ?

Vo ( initial velocity) = 1.5 m/s

a (acceleration) = .65 m/s^2

t (time) = 2.6 seconds

The equation you want is Vf = Vo + (a)(t).

Plugging in the variables gives Vf = 1.5 + (.65)(2.6).

The final velocity is 1.5 + 1.69, which comes out to +3.19 m/s.
