Need Help, Please Physics Homework, Final tomorrow Please

AI Thread Summary
To find the tension in the clothesline with a 3kg coat sagging at a 5-degree angle, one must resolve the forces acting along the line. For the car problem, applying the kinematic equation is necessary to determine the original speed after a deceleration of 4 m/s² over 40 meters. Participants are reminded to show their work for both problems to receive assistance. The discussions emphasize the importance of understanding force resolution and kinematic equations in solving physics problems. Clear problem-solving steps are essential for effective help in homework queries.

1)A 3kg heavy winter coat hangs in the middle of a clothesline causing it to sag by an angle of 5 degrees. Find the tension in the clothesline.

2). A car is traveling with a constant speed when the driver suddenly applies the brakes giving the car a deceleration of 4 m/s^2. If re car. Comes to a stop in a distance of 40 meters. What was re cars original speed?

Hi, the same rules apply here. You need to show your work before others can help you. The first one is just resolving forces along the clothesline. The second one requires one of the three basic kinematics equations.
 

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...
