Question

an object is protected vertically upward with speed √gR where R is the radius of earth and g is the acceleration due to grvity on surface of earth. find the maximum height attained by it??​

Answer 1

v^2 - u^2 = 2as

Taking downwards as negative we get,

v = 0

u = -√gR

s = ?

a = -g

i.e, 0-(-√gR)^2=2*-gs

-gR=-2gs

s=R/2.

Thank you must reply am i ri8 or wrong

Answer 2

Answer: R=h

Explanation:

You just have to use energy conservation
