A gun tilted upward at 41 degrees above the horizontal fires a bullet by a speed of 216 m/s. The bullet travels as a projectile and lands at the same height as the gun. Ignoring air resistance, answer the following.
1. What is the magnitude of the velocity of the bullet just before it hits the ground?
2. What is the magnitude of the vertical acceleration of the bullet after it leaves the barrel?
3. What is the magnitude of the velocity of the bullet at its highest point off the ground?
