Question

A race car accelerates uniformly at 19.3 m/s2. If the race car starts from rest how fast will it be going after 4.4 seconds.

Answer 1

Answer:

84.92 m/s

Explanation:

Given, a= 19.3 m/s²

           u=0 (as starts from rest)

           t= 4.4 s

By applying the formula-

        v = u + at

⇒    v = 0 + 19.3* 4.4 = 84.92 m/s.
