Question

A body is moving with a velocity 10m/s. If the motion is uniform, what will be the velocity after 10 seconds?

Answer 1

Answer:

Given -

• Initial Velocity, u = 10m/s
• Time, t = 10 sec

To find -

• Velocity after 10 seconds.

Solution -

As per the Question, the body is in uniform motion, So, it's acceleration will be 0 m/s.

$\\ \sf \: Acceleration = \dfrac{(v-u)}{t}\\ \\ \\ \implies \sf \:0 = \dfrac{(v - u)}{t} \\ \\ \\ \implies \sf \: 0 = \dfrac{(v - 10)}{10} \\ \\ \\ \implies \sf \: 0 \times 10 = v - 10 \\ \\ \\ \implies \sf \: 0 = v - 10 \\ \\ \\ \implies \sf{ \underline {\: 10 \: m \: per \: sec.}}$

Therefore, velocity after 10 sec will be 10 m/s.

Answer 2

Answer:

The velocity after 10 seconds will remain the same i.e. 10 m/s.

Explanation:

As per the data given in the question,

We have,

Initial Velocity of the body (u) = 10 m/s

Let Final Velocity of the body be v m/s

Time after which velocity is to be found  (t) = 10 seconds

Since, the body is in uniform motion,

so, its acceleration will be 0 m/s²

Applying the formula

$v=u+at\\v=10+0\times 10\\v=10\:m/s$

Hence, the velocity after 10 seconds will remain the same i.e. 10 m/s.
