Children slide down a frictionless water slide that ends at a height of 1.80 m above the pool. if a child starts from rest at point a and lands in the water at point b, a horizontal distance l = 3.55 m from the base of the slide, determine the height h of the water slide.

Explanation:

As we know that height of the slide is given as

so time taken by the child to hit the water from the slide is given as

now we will plug all data in it

now we know that the horizontal distance moved by it is given as

now by energy conservation

so height of point A is given as

a sonic boom is a loud boom that breaks the sound barrier
