A bullet is fired horizontally at a height of 1.3 meters and a velocity of 950 m/s. How long was the bullet in the air?

Any substance on this earth is directly dependent on the gravitational force. The bullet fired horizontally will also faced the gravitational pull force.

To calculate the time the object takes to hit the ground, we use the following equation:-

The bullet is travelling in the air hence it does not depend on the velocity bt the mass. The height taken by the bullet is h=1.3m.

After putting the value to the equation, the answer will be as follows:-

After solving the equation the value of time is 0.52 seconds

The bullet was 0.52 seconds in the air.

Explanation:

Horizontal Motion

It occurs when an object is thrown horizontally with a speed v from a height h.

The object describes a curved path ruled exclusively by gravity until it hits the ground.

To calculate the time the object takes to hit the ground, we use the following equation:

Note it doesn't depend on the initial velocity but on the height.

The bullet is fired horizontally at h=1.3 m, thus:

t = 0.52 s

The bullet was 0.52 seconds in the air.

kepler used the data from tycho blahe (his mentor) to construct the laws of planetary motion.

hi there!

out of the two, (b) precision would be more reasonable.   however, both a and b could be pretty reasonable.
