Question

A body is moving with 15 m/s is accelerated at 4m/s^2 calculate distance travelled by body in 8 sec​

Answer 1

Answer:

ANSWER

Given that,

The acceleration a=8m/s2

Initial velocity u=0m/s

We know that,

The displacement in the nth second

=u+a(n−21)

Now, the displacement in 5th second

  =0+8(5−21)

 =36m

Hence, the distance covered by it in fifth second is 36 m

Answer 2

Answer:

Given that,

The acceleration a=8m/s

2

Initial velocity u=0m/s

We know that,

The displacement in the nth second
