Question

If a body body start from rest and attain a velocity of su kish in 5 second, 5 find the accleration.​

Answer 1

Answer:

Given that,

A body starts from rest and moves with an acceleration of 2 m/s²

here,

Initial velocity of the body = 0 m/s

[because it was initially at rest]

Acceleration of the body = 2 m/s²

To find,

distance covered by body in the 10th second of its motion

We know that distance travelled in nth seconds

= u + a/2(2n - 1)

let the distance covered in 10th seconds be S10

here,

n = 10 s

initial velocity(u) = 0 m/s

acceleration(a) = 2 m/s²

putting the values

S10 = 0 + 2/2(2(10) - 1)

= 20 - 1

S10 = 19

so,

Distance travelled in 10th seconds

= 19 meter
