Question

starting from rest a body covers 15m in the 8th second of its journey. find the acceleration which is uniform and the distance covered in 7 sec and 8 sec​

Answer 1

Solution!

Given that,

The acceleration a=8m/s

2

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
