    Cart Incline
AI Thread Summary
Jill is trying to catch a shopping cart rolling downhill from a 3-degree incline, with the cart accelerating due to gravity. The cart's acceleration is calculated as 9.81 sin(3°), while Jill's acceleration is 2 m/s² plus the same gravitational component. To determine how far the cart rolls before Jill catches it, both their positions must be equated using the formula x = x_0 + v_0*t + 1/2at². Jill starts from rest at an initial position of zero, while the cart starts 50 meters downhill. The discussion focuses on setting the equations for both Jill and the cart equal to find the distance traveled before Jill catches the cart.

Jill has just gotten out of her car in the grocery store parking lot. The parking lot is on a hill and is tilted 3 degrees. Fifty meters downhill from Jill, a little old lady let's go of a fully loaded shopping cart. The cart, with frictionless wheels, starts to roll straight downhill. Jill immediately starts to sprint after the cart with her top acceleration of 2 m/s^2

How far has the cart rolled before jill catches it?

I know you need to set two formulas equal to each other, but I don't know which formulas :cry:

EDIT: I started off by drawing it out and taking the sin of 3 degrees, .0523 and multiplying it by 9.8 to get the acceleration of the cart, I don't know where to go from there

bump, anyone
 
the cart's acceleration is NOT 9.81 but 9.81sin(3°)

Jill's initial position and velocity is ZERO, her acceleration is 2 + 9.81sin(3°) due to gravity also.

For the cart : initial velocity is zero; initial position is 50 (i assume the 50m downward is along the hill and not measured horizontally)...This is all you need

Use x = x_0 + v_0*t + 1/2at²

where x_0 is initial position and v_0 is initial velocity

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...
