Question

The speed of a body increases by 2 m/s every second. Write its acceleration. Is it in a uniform motion?​

Answer 1

its acceleration will be 2 and it is not uniform. hhhh

Answer 2

Consider initial speed be "u" m/s.
Now it's speed increases by 2 m/s every second.
Now after 1 second:
speed, v = (u + 2) m/s

As we know Newton's 1st law–
v = u + at
(u + 2) = u + a(1)
a = 2m/s²

OR,

a = (v – u)/t
a = ((u + 2) – u)/(1)
a = 2m/s²

Now since it have an acceleration, so it will not be in uniform motion.
For uniform motion, a = 0.

Thankyou!!!
