AI Thread Summary
To determine the time a kangaroo spends in the air while jumping to a height of 3.0 meters, the correct approach involves using kinematic equations. The initial calculations yielded an incorrect time of 5.622 seconds. The discussion references a previous thread that may provide additional insights or methods for solving similar problems. Participants are encouraged to verify their calculations and consider the correct application of physics principles. Accurate problem-solving is essential for achieving the correct result.

The Attempt at a Solution


i got 5.622 as an answer but that's not right.

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...
