AI Thread Summary
The motorboat's engine delivers 30.0 kW while moving at 15.0 m/s, resulting in a force of 2000 N. When towed at the same speed, the tension in the towline should equal this force. The discussion confirms that the force required to maintain the speed remains consistent, regardless of whether the boat is self-propelled or towed. The original poster successfully resolved their question with community assistance. Understanding the relationship between power, force, and speed is crucial for solving similar problems.

Homework Statement



The engine of a motorboat delivers 30.0 kW to the propeller while the boat is moving at 15.0m/s. What would be the tension in the towline if the boat were being towed at the same speed?


The Attempt at a Solution



I used P= FV to find F= 2000N, but now I don't know how to find tension. Please help!

Please excuse me if I am wrong, but unless anyone says otherwise, I believe that you have found the answer.
You found the force required to move the boat at 15m/s (F=2kN). So to move that boat at the same speed (15m/s) should require the same amount of force. It's just being applied in a different way.
 
Thanks so much! I figured it out a little after I posted the question, but thanks for confirming my thoughts!
 

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...
