A cannonball is launched with a speed of 170 m/s at 40 degrees above the horizontal. Find the missing components into which is the resolved. Thank you in advanced!
Just decompose the speed into horisontal speed (remains constant) and vertical speed (decelerated by g). You could then find out how far it goes, assuming the ball starts from ground level -- find out when does the ball get back to ground level in the vertical one and multiply the time by the horisontal speed.
