A rival pirate fires his volley back at the same 3.5m above the sea but at an angle of 23 coincidentally this scurvy dogs cannon also fires at 120 m/s also strangely coincidentally this cannonball also misses the sea how far did this canon ball travel?

1.065 km

Explanation:

The horizontal and vertical component of the canon ball when it's fired is

If we ignore air resistance, then gravitational acceleration g = -9.8m/s2 is the only thing that affects the vertical motion of the cannon ball. We can use the following equation to calculate the time it stays on air after it traveling h = -3.5m (down below the firing point) vertically

t = -0.07 or t = 9.64

Since t can only be positive we will pick t = 9.64

This is also the time it takes for the cannon ball to travel horizontally at the rate of 110.46 m/s

or 1.065 km

from 1609, galileo galilei used the recently invented telescope to observe the sun, moon and planets. he saw the mountains and craters of the moon, and for the first time revealed the planets to be worlds in their own right. galileo also provided strong observational evidence that planets orbited the sun.

his discoveries about the moon, jupiter's moons, venus, and sunspots supported the idea that the sun - not the earth - was the center of the universe, as was commonly believed at the time.galileo turned his gaze toward venus, the brightest celestial object in the sky - other than the sun and the moon.

the answer is 100. i just did this lesson and got a 100% on it. : )
