A cannon is pointed at 60 degrees angle relative to flat horizontal field. it fires a projectile with a muzzle speed of 1500 ft/s Then the gunner changer the angle to 30 reload the cannon and 5.0 seconds later , fire. What is the required muzzle speed for teh projectile to hit the ground at the same time as the first?
