Question

1. A bullet leaves the barrel of a gun at a speed of 220 m/s at an angle of 10 degrees above the horizontal. At the moment the bullet leaves the barrel, the acceleration of the bullet is:
2. 0
3. 220 m/s2 to the right
4. 9.8 m/s2 upward
5. 9.8 m/s2 downward

Answer 1

At the moment the bullet leaves the barrel, the bullet moves under the gravity only. Therefore, the acceleration of the bullet equals 9.8 m\s² directed downward.

Answer:

9.8 m\s²,directed downward.
