Jill's Sprint After Shopping Cart: Physics Kinematics

AI Thread Summary
Jill is sprinting after a shopping cart that rolls downhill from a 3-degree incline. The cart has frictionless wheels and accelerates due to gravity, while Jill has a maximum acceleration of 2.0 m/s². Participants discuss using kinematics equations to determine the distance the cart rolls before Jill catches it, emphasizing the importance of time as a parameter. The significance of the 3-degree angle is clarified, as it relates to the cart's acceleration down the slope. The conversation concludes with a focus on solving the problem using appropriate kinematic equations.

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 2.0m/s^2

how far has the cart rolled before jill catches it.

i was thinking having a kinematics equation for both, and then solving one of them for a variable that i could substitute into the other equation...yes?

yes time t will be perameter.

which kinematics equation should i use, and will it be the same for both of them? i can't do much without velocities :confused:

what is the significance of 3 degrees because they already gave us the acceleration, is this the accel of the cart?
 
solved. thanks
 
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...
