Question

An object moving along a straight line at 30m/s undergoes an acceleration of 5m/s^2.After 2 secs its speed will be:

Answer 1

Given :-

Initial Velocity of object = u = 30 ms-¹

Acceleration of object = a = 5 ms-²

Time = t = 2 s

Here, we are required to find the final Velocity of object. So we will use first equation of Motion for this question.

v = u + at

v = 30 + 5 × 2

v = 30 + 10

v = 40 ms-¹.

Hence,

The velocity after 2s = V = 40 m/s.
