Answer:
2.1 s
Explanation:
The motion of the ball is a projectile motion. We know that the horizontal range of the ball is
And that the initial speed of the ball is
at an angle of
So, the horizontal speed of the ball (which is constant during the entire motion) is
And since the horizontal range is 50 m, the time taken for the ball to cover this distance was
which is the time the ball spent in air.
Relative motion is the motion of an object relative to another object,
or as it would appear to an observer stuck to the other object and
riding on it.
