    Boat River Speed
AI Thread Summary
The maximum velocity of the fishing boat in the river can reach 4m/s west when combining its speed with the river's current. The minimum speed of the boat, when moving against the current, is effectively 0m/s relative to the riverbank if it travels at 2m/s east while the river flows at 2m/s west. This means that the boat's movement would appear stationary to an observer on the riverbank. The discussion clarifies the concepts of maximum and minimum speeds in relation to the current. Understanding these dynamics is essential for calculating a boat's effective speed in flowing water.

A fishing boat with a max. velocity of 2m/s is in a river that is flowing at 2m/s west.

a. what is the maximum velocity the boat can obtain?
is it 4m/s?


b. what is the minimum speed?
this question i need help answering...

"a. what is the maximum velocity the boat can obtain?

The max speed is 4m/s; the max velocity is 4m/s west (magnitude and direction).

For part b, if you boat goes 2m/s east with respect to the water, and the water goes 2m/s west with repect to the river bank, what is the boat's speed with respect to the river bank? How would the boat appear to be moving to someone standing on the riverbank?
 
so it should be 0 m/s?
 
Yep!
 
thanks ;]
 
You're welcome.

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
