Question

Va rog ajutati ma repedee​

Answer 1

$v_{scara}=2 m/s\\l_{scara}=4 m\\v_{om}=1 m/s\\l_{scara}=t_{repaus}*v_{scara}=>t_{repaus}=\frac{l_{scara}}{v_{scara}}=\frac{4}{2}=2 s=> t_{repaus}=2s\\v_{totala}=v_{scara}+v_{om}=2+1=3 m/s\\l_{scara}=t_{urca}*v_{totala}=>t_{urca}=\frac{l_{scara}}{v_{totala}}=\frac{4}{3}= 1,33s=>t_{urca}=1,33 s$
