Explanation:
From the law of conservation of linear momentum
where
and
are masses of bullet and stones respectively,
and
are the initial velocities of bullet and stone respectively,
and
are the final velocities of bullet and stone respectively
Substituting 6g=0.006 Kg for mass of bullet, 0.1Kg for mass of stone, 350 m/s for initial velocity of bullet and 250 m/s as final velocity for stone but initial velocity of stone is zero
Substituting 21 for and 15 for
To find direction
Therefore, magnitude is 25.8 m/s and direction is
Answer:
A. 79.3 keV
Explanation:
Because the procedure involves many steps for its resolution and it works faster on paper and pencil, the detailed solution of this exercise is attached as a scanned image of the procedure for review.
In the procedure, the initial values of the problem and the replacement of these values with the correct formulas for this process are taken into account.
