So i know the total time is 8.6 s t1 + t2 = 8.6s And from the (v^2 - v0^2 = 2as) i will get that after 15m the velocity which is also the highest velocity v^2 = 30a And then after that the velocity will be constant (s = v*t) 45/t2 Now i am stuck here because i have 3 equations but 4...

Momentum of a girl: $$p_{1} = m_{1}v_{1} = 50 * 5 = 250$$ Momentum of an idle boat: $$p_{2} = m_{2}v_{2} = 150 * 0 = 0$$ So if the girl jumps into the boat, the two "systems" connect with each other. The momentum is passed onto the boat (?): $$p_{1} = p_{2}$$ $$m_{1}v_{1} = m_{2}v_{2}$$...

What I can't understand from the problem is that whether she stays at a certain pub for M hours, or she visits more pubs and goes home after M hours. If it's the first case, then I think the answer is ##\frac{M}{24}\frac{1}{N}##. This problem is posted as a harder one so I suppose it has to...
