Question

An object is thrown vertically upwards with a velocity u, the greatest height h to which it will rise before falling back is given by: A. u/g B. u 2 /2g C. u 2 /g D. u/2g

Philoid · Accepted Answer

Since, The maximum height will be reached by the object when its v will be equal to zero.

We know:

v² = u² - 2gh

(0)² = u² - 2gh

u² = 2gh

h = u²/ 2g

An object is thrown vertically upwards with a velocity u, the greatest height h to which it will rise before falling back is given by:A. u/g B. u2/2gC. u2/g D. u/2g

An object is thrown vertically upwards with a velocity u, the greatest height h to which it will rise before falling back is given by:
A. u/g B. u²/2g

C. u²/g D. u/2g
