A cannonball is launched at ground level with a speed of 30 m/s at an angle of 65 degrees to the horizontal. How much later does it hit the ground? What is the football's max height and horizontal distance traveled before hitting the ground? What is the velocity of the ball at 2 seconds?
Total Time= 2.67 s, Height= 38.3 m, Range= 71.3m, $V_f$= 14.8 m/s
Total Time= 5.55 s, Height= 35.6 m, Range= 73.5m, $V_f$= 7.2 m/s
Total Time= 2.67 s, Height= 38.1 m, Range= 70.5 m, $V_f$= 12.7 m/s
Total Time= 5.55 s, Height= 37.7 m, Range= 70.5m, $V_f$= 14.8 m/s
