Question

A rifle fires a bullet toward a target 102 m away. If the bullet travels at a supersonic speed of 585 m/s, how long does the bullet take to reach the target? Show all your work.

a. 0.174 seconds
b. 0.174 milliseconds
c. 0.174 microseconds
d. 0.174 nanoseconds

Answer 1

The bullet takes 0.174 seconds to reach the target.

So, the correct answer is option A.

Step-by-step explanation:

To calculate the time it takes for the bullet to reach the target, we can use the equation:

Time = Distance / Velocity

Plugging in the given values, we have:

Time = 102 m / 585 m/s = 0.174 seconds

Therefore, the bullet takes 0.174 seconds to reach the target.

So, the correct answer is option A.

Answer 2

The correct answer is that the bullet takes approximately 0.174 seconds to reach the target, calculated by dividing the distance to the target (102 m) by the bullet's speed (585 m/s). This physics problem uses the principle of kinematics.

Step-by-step explanation:

The correct answer is option a. To calculate the time it takes for a bullet to reach a target given its velocity and the distance, you would use the formula t = distance / velocity. In this case, the bullet travels at a velocity of 585 m/s and the target is 102 meters away. By dividing the distance by the velocity, you get the time it takes for the bullet to reach the target:

time = 102 m / 585 m/s = 0.1744... seconds

When rounded to the nearest thousandth, the time is approximately 0.174 seconds, which is answer choice a. This calculation involves basic kinematics in one dimension.

The correct answer is option a. 0.174 seconds.

To find the time it takes for the bullet to reach the target, we can use the equation:

time = distance / velocity

Given that the distance is 102 m and the velocity is 585 m/s, we can plug these values into the equation:

time = 102 m / 585 m/s = 0.174 seconds

Therefore, the bullet takes 0.174 seconds to reach the target.
