Question

A car starts from rest and moves with an uniform acceleration of 2m/s2 .What will be its velocity after it covers a distance of 49m?​

Answer 1

Answer:

Time = 7 sec

Explanation:

In this question,

Initial velocity (u) = 0 ( it starts from rest )

Acceleration (a) = 2m/s²

Distance (s) = 49m

Time (t) = ?? (We need to find )

By using, s = ut+1/2at²

By putting values,

49 = 1/2*2*t²

Time = 7 sec
