Answer:
The maximum height above its initial position is:

Explanation:
Using momentum conservation:
(1)
Where:
- m(b) is the mass of the bullet
- m(B) is the mass of the block
- v(ib) is the initial velocity of the bullet
- v(fb) is the final velocity of the bullet
- v(fB) is the final velocity of the block
Let's find v(fb) using equation (1)
We need to find the maximum height, it means that all kinetic energy converts into gravitational potential energy.




I hope it helps you!
A unit of acceleration needs a unit of length in the numerator
and a squared unit of time in the denominator.
Example: meters / second²
feet / minute²
smoots / hour²
furlongs / fortnight² .
Ideally, in order to completely describe an acceleration vector,
you also need to state a direction.

Answer:
The box displacement after 6 seconds is 66 meters.
Explanation:
Let suppose that velocity given in statement represents the initial velocity of the box and, likewise, the box accelerates at constant rate. Then, the displacement of the object (
), in meters, can be determined by the following expression:
(1)
Where:
- Initial velocity, in meters per second.
- Time, in seconds.
- Acceleration, in meters per square second.
If we know that
,
and
, then the box displacement after 6 seconds is:

The box displacement after 6 seconds is 66 meters.
