Answer 2

Given Information:

A bullet with a velocity of 600 m/s strikes a soil embankment and penetrates it to a depth of 0.3 m. We need to determine the acceleration and the time of motion of the bullet inside the embankment.

Solution:

To find the acceleration and time of motion of the bullet inside the embankment, we can use the equations of motion.

Let's assume: - Initial velocity of the bullet outside the embankment, V0 = 600 m/s - Final velocity of the bullet inside the embankment, V = 0 m/s - Distance traveled by the bullet inside the embankment, S = 0.3 m

Using the equation of motion: V^2 = V0^2 + 2aS, we can find the acceleration (a) inside the embankment.

V^2 = V0^2 + 2aS 0^2 = (600 m/s)^2 + 2a(0.3 m) 0 = 360000 m^2/s^2 + 0.6a -0.6a = 360000 m^2/s^2 a = -600000 m^2/s^2

Therefore, the acceleration of the bullet inside the embankment is -600000 m^2/s^2.

Now, let's find the time of motion (t) of the bullet inside the embankment using the equation of motion: V = V0 + at.

V = V0 + at 0 = 600 m/s + (-600000 m^2/s^2)t -600000t = -600 m/s t = (-600 m/s) / (-600000 m^2/s^2) t = 0.001 s

Therefore, the time of motion of the bullet inside the embankment is 0.001 seconds.

Answer:

The acceleration of the bullet inside the embankment is -600000 m^2/s^2, and the time of motion of the bullet inside the embankment is 0.001 seconds.
