Question

a body start from rest with a uniform acceleration of 2 m per second find distance covered by it in 2 second​

Answer 1

Explanation:

Given that,

Body start from rest I.e u=0; a=2m/s^2 ; t=2s

Formula for calculating covered distance is,

S=ut+1/2 at^2

Where,

S=Distance covered by the body.

a=Acceleration of the body.

t=Total time taken by the body.

After putting given datas in our formula

That is,. S=ut + 1/2 at^2 =>0+1/2 ×2×2^2= 4m.ans

Happy learning!!

Mark me as a brainlist thankyou......

Answer 2

Answer:

8m

Explanation:

using acceleration formula:

2= acc

2 = time(t)

0(because object was at rest)= initial speed(u) /  final speed(v) = ?

a= v-u/t

2= v - 0 / 2

4 = v

using speed formula:

s=d/t

4 = d/ 2

8 = d
