Swimmer and River (Relative Velocity)

AI Thread Summary
The discussion revolves around a swimmer aiming to reach a point 30 degrees upstream across a river with a current of 5 m/s. The swimmer's velocity relative to the water is 5√3 m/s. Clarification is provided that the 30-degree angle refers to the point where the swimmer's trajectory intersects the opposite bank. The participants discuss the implications of the swimmer's angle of approach to successfully reach the target point. Understanding the relative velocities is crucial for solving the problem effectively.

Homework Statement


A swimmer is to reach at a point 30 degree upstream on the other side of a river flowing with velocity 5 m/s. The velocity of the swimmer w.r.t. water is 5\sqrt{3}. The swimmer should steer at an angle??


The Attempt at a Solution



I am unable to guess the scenario. What does this mean?
A swimmer is to reach at a point 30 degree upstream on the other side

A swimmer is to reach at a point 30 degree upstream on the other side

Hi ritwik06! :smile:

It just means where the line at 30º to straight-across hits the other bank. :wink:

(so straight-across would be 0º upstream)
 

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'

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...
