Question

An object is projected vertically upward with a speed √gR where R is the radius of the Earth and g is the acceleration due to gravity on the surface of the earth. Find the maximum height attained by it​

Answer 1

Answer:

2R

Explanation:

Apply Conservation of Mech Energy

U(f)-U(i)=KE(f)-KE(i)

Replace g by GMm/(R^2).

where G is universal gravitational const and M denotes mass of earth while m is mass of body
