Car's Final Velocity and Distance Traveled in Braking Period

AI Thread Summary
The discussion focuses on calculating a car's final velocity and distance traveled during its braking period after an initial acceleration. The car accelerates from rest at +1.3 m/s² for 5.9 seconds, followed by a braking phase with a deceleration of -2.1 m/s² for 1.60 seconds. Participants are encouraged to share their thought processes and any difficulties encountered while applying relevant physics concepts and formulas. The thread emphasizes the importance of breaking down the problem into manageable parts to find solutions. Engaging with the community can provide clarity on the calculations involved.

A car starts from rest and travels for 5.9 s with a uniform acceleration of +1.3 m/s2. The driver then applies the brakes, causing a uniform acceleration of -2.1 m/s2. The breaks are applied for 1.60 s.
(a) How fast is the car going at the end of the braking period?

(b) How far has the car gone from its start?

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...
