Question

body moving with a velocity 'u' covers a distance of 20m in 10 s with a uniform velocity what is the acceleration of the body also mention the direction​

Answer 1

ANSWER:

Given:

d = 20 m

t = 10 s

u = 20 / 10 = 2 m/s

Acceleration is the rate of change of velocity.

Since the velocity is constant or uniform or there is no change in it,

there will be no acceleration as body is moving with a uniform velocity.

Since there is no acceleration there will be no direction to it as well.

We can also verify that by using the second equation of motion:

s = ut + 1/2 at ^ 2

20 = 2*10 + 1/2 a*10*10

20 = 20 + 1/2*100*a

20 = 20 + 50 a

( 20 - 20 ) / 50 = a

0 /50 = a

Therefore, a = 0 m / s^2
