Question

An object is starting from rest and moving with an acceleration of 2 m/s2. What will be its velocity after 10 second?
​

Answer 1

Answer:

u=0

v=?

t=10s

a=2m/s²

a=v-u/t

2=v-0/10

2= v/10

v=10×2=20m/s

Answer 2

We know that the formula of velocity is;

v = u + at

Now, as per the question,

Initial velocity = u = 0

And, Acceleration = a = 2 $m/s^2$

Time = t = 10 seconds

Then, final velocity = v = u + at

v = 0 + 2 × 10 m/s

v = 20 m/s

Ans) After 10 seconds, the velocity will be 20 m/s
