Modifying a Car: 0-47 mph Distance Covered

AI Thread Summary
To determine the distance covered by a car accelerating from 0 to 47 mph, one can use kinematic equations under the assumption of constant acceleration. The engine specifications include a 2.0 L, 4-cylinder engine with 146 hp and a curb weight of 1418 kg, with a 0-60 mph time of 8.6 seconds. However, it is noted that real-world car acceleration is not constant, which complicates calculations. Converting speeds to meters per second may aid in the calculations. Accurate distance estimation requires considering varying acceleration rates rather than assuming uniform acceleration.

First, I am not a student. I'm looking to do some modifications to a car and I'm not sure what to do.

Homework Statement



a 2.0 L, 4 cylinder engine w/ 146 hp

curb weight = 1418 kg

0-60 mph time of 8.6 s

0.25 mile time of 16.7 s at a top speed of 81.8 mph

What distance (miles) would be covered going from 0-47 mph?


Homework Equations



1 hour = 3600 s
60 mph = 0.0167 miles/s
47 mph = 0.013056 miles/s

The Attempt at a Solution

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...
