PLEASE HELP WITH THESE TWO QUESTIONS- SHOW WORK ! THANK YOU !
For a projectile fired at 28 degrees from a height of 0 m, how long does it take to hit the ground? Remember that a_y=-9.8 m/s^2. Initial velocity of the projectile is 42 m/s. And second question is - using your answer from that above question, how far did the cannonball travel in the horizontal direction?
