Answer:
P = (2 + 3) * V where V is their initial speed (total momentum)
P = 2 * 10 + 3 * Vx where Vx here would be V3
If the initial momentum is not known how can one determine the final velocity of the 3 kg obj.
Also work depends on the sum of the velocities
W (initial) = 1/2 (2 + 3) V^2 the initial kinetic energy
W (final) = 1/2 * 2 * V2^2 + 1/2 * 3 * V3^2
It appears that more information is required for this problem
Answer: Think of it like this, in space there is no gravity. This makes it very hard to move. This is why spacesuits have mini propellers. And the reason why rockets well... have rockets.
Answer:
<h3>Two-track correctional system is a system of consisting two correctional institutions for criminals.</h3>
Explanation:
- The two-track correctional system is a correctional system that consists of two separate correctional institutions for criminals. One institution for juveniles and one for adult criminals.
- No, two-track correctional system would not work better in our country. There are many cases of serious juvenile crimes in our country. Juveniles who commit serious or atrocious crimes should be dealt strictly in an adult or criminal court without exemption.
- Yes, this would reduce the percentage of offenders re-entering the system because juveniles incarcerated for serious crimes would be locked up in the prison instead of being acquitted after a short detention.
- This would stop them from committing similar offences and would reduce potential crimes from ex-convicted juveniles.
Answer:
(a)7.48331 Km
(b) Directly above the tomb
(c) 12.53 degrees
Explanation:
Given that the distance is 3.5 Km, converted to meters we obtain 3500 m
Using the formula
where s is the distance and t is time, taking acceleration due to gravity as 9.8 then
t = 26.72 sec
We know that speed=distance/time hence to get the distance in part (a)
Distance=Speed*time
280 *26.72 = 7483.31 m converted to Km we obtain 7.48331 Km
(b)directly above the bomb
(c)
