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

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.

close lines strong magnet less close weaker

that tool is called an altimeter which measures your altitude which can be used to tell which atmosphere you are currently in, including the stratosphere.

hope this ! : )
