Denisse Whitaker · Answer 1

12200 ft/s

Explanation:

The question is on constant acceleration

→Uniform acceleration motion is given by⇒⇒⇒ Vf=Vo + at ... (a)

→Where Vf = final velocity=?

Vo=initial velocity = 2200 ft/s

a = acceleration = 1000ft/s²

t = 10.0 sec

Substitute values in (a) above

Vf=Vo + at

Vf = 2200 + (1000*10) = 12200 ft/s
