Answer:
45.09 m/s^2
Explanation:
from the question we were given the following parameters
mass = 931.9 kg
initial velocity (V1) = 0 m/s ( since it started from rest )
final velocity (V2) = 25.7 m/s
time (t) = 0.57 s
The average acceleration is given by:
a = ( V2 - V1 ) / t
therefore
a = (25.7 - 0) / 0.57 = 45.09 m/s^2
The moon lacks an atmosphere compared to the Earth. Hope this helps!
The height of the bullet when the velocity is zero is 256 ft.
<h3>Height of the bullet when the velocity is zero </h3>
The height of the bullet when the velocity is zero is determined by taking derivative of the function as shown below;

The height of the bullet at this time is calculated as follows;
