Question

a body is thrown vertically upward such that the distance travelled by it in fifth and sixth seconds are equal the maximum height reached by the body is
​

Answer 1

Explanation:

Let us check if the body travels the same distance in 5th second when going up and in 6th second when coming down. The ball covers 5 m in the upward direction in the 5th second. Xn = 0 + ½ ×10× (2×1–1)= 5×1 =5m. So the highest point reached by the ball is 125 m from the point of its being thrown up.
