If an object is thrown directly upwards remains in the air for 5.6s before it returns to its original position, how long did it take to reach its maximum height?

The study of matter is called physic.

The correct answer is 2.8s.

According to the question, the object is thrown upwards and it falls back to the ground.

The total time taken by the object is 5.6s.

The total distance of the object is shown as follows:-

H1 is the vertical upward distance and the H2 is the downward distance.

Both the height is the same then the formula is as follows:-

Hence, the time taken by the object to reach the ground is 2.8sec.
