The time of flight of the ball is 3.08 s
Explanation:
The motion of the cannonball is a projectile motion, consisting of two motions:
- A uniform motion (constant velocity) along the horizontal direction
- An accelerated motion with constant acceleration along the vertical direction
Here we can solve the problem just by analyzing the horizontal motion. In fact, we know that:
u = 24 m/s is the initial velocity of the ball
is the angle of projection
d = 56.6 m is the range of the ball (the horizontal distance covered)
First of all, we can find the initial velocity in the horizontal direction:
We know that this horizontal velocity is constant, so it is related to the range by:
where t is the time of flight of the ball; and solving for t, we find
