Acannonball is catapulted toward a castle. the cannonball’s velocity when it leaves the catapult is 51.6 m/s at an angle of 37.0° with respect to the horizontal, and the cannonball is 7.00 m above the ground at this time. the y-axis points up. what is the y-component of the cannonball’s velocity just before it lands?

Explanation:

From the exercise we know the cannonball's initial velocity, the angle which its released with respect to the horizontal and its initial height

If we want to know whats the y-component of velocity we need to use the following formula:

Knowing that

So, the cannonball's y-component of velocity is

50 inches should be the resultant vector
