| Test #5 / Тест 5 ошибка - решение | Danil Morozov | 1192. Мячик во сне | 31 янв 2024 16:52 | 1 |
If you are getting an error on test 5 then use double instead of float.
Если у вас ошибка при 5ом тесте, используйте переменные double вместо float. |
| If you have WA#2 with Python solution but, for some reason, you are sure that your solution is a piece of Art | iron_orc | 1192. Мячик во сне | 23 янв 2022 20:30 | 1 |
>>> print(round(0.0))
>>> 0.0
But
"The output should contain the required distance in meters rounded to two fractional digits"
So don't forget to use string formatting to provide 2 digits after comma
Real test case:
5 90 2.50
0.00 |
| if you have good solution, but programme was not accepted / Если ваша программа работает, но почему-то не принимается | Egor Sibriaev | 1192. Мячик во сне | 18 дек 2021 16:34 | 1 |
try changing the cycle: while(energy > 0.01) to while (energy > 0.00000000001)
Maybe this will help you
Попробуйте поменять цикл while (energy > 0.01) на while (energy > 0.00000000001)
Возможно, это поможет |

use
while (v < 0.01) Thank u so much... ^_^ Use geometric series.
1 + 1/k + 1/k^2 + ... = 1 / (1 - 1/k) |

A TIP esbybb 20 июн 2015 18:36 1. Calculate S
2. Total S = S+S/k+S/k^2+S/k^3.. |
| A few description problems | Kuros | 1192. Мячик во сне | 6 фев 2014 20:20 | 1 |
1) "after every fall, the kinetic energy of the ball decreases by a factor of K". So if K > 1, that means the energy becomes negative? E_2 = E_1 - E_1*K might be interpreted to be what you mean when you say something decreases by some factor.
2) "Your task is to determine the maximal distance from the point of throwing that the ball can fly." If the ball is pitched straight up, it will fly some maximal distance from the point of throwing before it reaches the ground again. You should probably exactly what you mean. |

Should it be geometry or physics ??? |
| It seems like that the author don't know the difference between speed and engery. | zhougelin | 1192. Мячик во сне | 5 дек 2008 16:27 | 5 |
Edited by author 08.09.2004 19:43 I don't think so.
T ~ V^2, assuming that gives ac hmm... i think the same. In each jump energy decreases K times, then (E = mv^2/2) speed decreases sqrt(k) times.
But my solution, which assuming that speed descreases k times (not sqrt(k)), got AC... Strange
Sorry for my poor English=) No,you are wrong,it's correct.
Each time v decreases in sqrt(k) times,but we use Vx*Vy,so it decreases in k times. I agree with you
kinetic engergy decreases in K times
speed decreases in sqrt(K) times
Because E=1/2*m*v^2

Nice joke!
I can't use constant PI (WA#3), I must used only number 3.1415926535!
Good test #3!
I thought this test can't be maked. But I was mistaken. :)
Read the condition!
It's answer for all you questions.
It's helped me. :)
And maybe helped you. |
