Question

a body is thrown vertically upward from ground it reaches a height of 100 m in 5 sec at what time will it reach the groundfrom maximum height position\

Answer 1

Answer:

Time to reach maximum height is 4.5 seconds.

Explanation:

We have to use the fundamental equAtions of uniformly accelerated motion.

I have taken the downward direction of g as negative and the value of g is taken as 10m/s^2. If you take it as 9.8, the values may be slightly different. But mostly it will be given in the question.

The time to reach the topmost point is same as that to reach the ground from the topmost point.

So the time is 4.5s

I have attached the answer.

Hope you understood it.
