Please answer me fast in paper then i will definitely mark you as a brainlist ​

Answer 1

Answer:

The distance covered by the body is 85 m.

Explanation:

Given that,

Acceleration  

Initial velocity u = 7 m/s

Time t = 5 second

Using equation of motion

......(I)

Put the value in equation (I)

The distance in 5 sec

The distance in 4 sec

Now, the distance covered by the body in 5th sec

Hence, The distance covered by the body is 85 m.
