Question

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

10s?Is the velocity a vector or scalar quantity?​

Answer 1

Answer:

Correct answer is 10m/s.

Answer 2

Given :

Initial velocity = 10 m/s

Time taken = 10s

To find :

Velocity after 10s

Solution :

As given in the question that the body is in uniform motion. So the acceleration will be zero

$a = \frac{(v - u)}{t} \\ \\ 0 = \frac{(v - 10)}{10} \\ \\ 0 \times 10 = v - 10 \\ 0 = v - 10 \\ v = 10 \: m {s}^{ - 1}$

So, the velocity after 10s is 10 m/s
