Example 9 a particle is projected from the surface of earth wl an initial speed of 4.0 km/s. find the maximum height attained by the particle. radius of earth 6400 km, and g 9.8m/s

Answer : The maximum height attained by the particle is 935 km.

Explanation :

The formula used for the maximum height attained by the particle is,

where,

h = height of the particle = ?

v = speed of the particle =

g = acceleration due to gravity =

R = radius of earth =

Now put all the given values in the above formula, we get:

Therefore, the maximum height attained by the particle is 935 km.
