Question

At what angle of elevation should a projectile be projected with velocity 20ms-1 so as to reach maximum height

Answer 1

Answer:

height = ???

Explanation:

Answer 2

Dear student,

It is given that the initial velocity of the projectile is 20 m/s. We need to find the angle of elevation at which when the body is projected gives maximum height.

By the concepts of projectile motion in 2-D, we know that, maximum height is obtained when a body is projected at perpendicular to the horizontal surface.

Hence, the angle of elevation should be 90° to reach the maximum possible height.
