The cannonball will be 311.8 m far in meter when it travels horizontally
A projectile is any object like stone, ball or javelin that take a parabolic path when thrown into the air.
The following parameters are given from the question
Resolve the initial velocity into horizontal and vertical components. That is,
To calculate the range that is, the horizontal distance, will can first calculate the total time take by the ball to reach the ground.
Total time T = 2usinФ / g
Substitute all the parameters
T = (2 x 60sin30) / 10
T = (2 x 30) / 10
T = 60 / 10
T = 6 s
The horizontal distance R = ucosФ x T
R = 60 x cos 30 x 6
R = 311.77 m
Therefore, the cannonball will travel 311.8 m approximately horizontally.
