AI Thread Summary
A jogger exerts a force of 29N against air resistance while maintaining a velocity of 4.0m/s. The power expended by the jogger can be calculated using the formula P = F * v, where F is the force and v is the velocity. The initial attempt calculated power as 116 kgm/s, but this is incorrect due to unit misinterpretation. The correct power output should be expressed in watts, where 1 watt equals 1 joule per second. The discussion emphasizes the importance of using proper units when calculating power.

1. Suppose a Jogger has to exert a force of 29N against air resistance to maintain a velocity of +4.0m/s. At what rate is the jogger expending energy?2. P= F*(tf-ti)3. Attempt solution was
P= 116kgm/s

The units are wrong for power. What do you get if you multiply Newtons by m/s?
 

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 'Collision of a bullet on a rod-string system: query'

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

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...
