Question

what is projectile motion? find the formula of following (a) maximum height (b) range (c) time of flight​

Answer 1

Answer:

concept

The average velocity of a projectile between the instant it crosses one third the maximum height. It is projected with u making an angle θ with the vertical.

There will be a pair of points for which vertical velocities at the same height are in opposite direction and therefore their average sum =0

It is the horizontal velocity which is uniform and hence v

av

=u

x

=ucosθ

For a general point:

Displacement in Y-direction:

y=usinθ×t−

Displacement in X-direction:

x=ucosθ×t

Now in order to calculate average velocity:

Average Velocity =
