#4834

Notwen a auzit de descoperirile prietenului său de pe Pământ şi a decis să studieze şi el legile gravitaţiei pe planeta sa. Pentru aceasta a conceput un experiment, care utilizează două drepte (o dreaptă verticală şi o dreaptă oblică, înclinată la un unghi oarecare faţă de orizontală) şi un super-măr (care, pentru a simplifica analiza, este considerat punctiform). Cunoscând distanţa x la care se află super-mărul față de dreapta verticală la începutul experimentului:
1. Determinați numărul de ciocniri ale super-mărului cu dreapta verticală.
2. Determinați numărul de ciocniri ale super-mărului cu dreapta înclinată.
