Finding net force and net acceleration

AI Thread Summary
To find the net force and net acceleration of a 2500 kg hamburger sliding down a 45-degree ramp with a coefficient of kinetic friction of 0.597, it's essential to analyze the forces acting on the hamburger. The gravitational force must be resolved into components, with the parallel component driving the motion down the ramp and the frictional force opposing it. A free body diagram is recommended to visualize these forces and calculate the net force accurately. The net force can then be used to determine the acceleration using Newton's second law. Understanding these concepts is crucial for solving the problem effectively.

Homework Statement


A hamburger with a mass of 2500 kg was slided down a ramp that has a 45 degree incline, and the coefficient of kinetic friction betwen the hamburger and the ramp is .597. What is the net force acting on the hamburger? What is the net acceleration?

Homework Equations


Mass of burger= 2500 kg
mew k = .597

The Attempt at a Solution


The net force is mass times acceleration. But i don't have acceleration.

You have the acceleration due to gravity and the force due to friction. You have to find the component of the acceleration due to gravity which points down the ramp.
 
but I'm not sure if the object is at equilibrium?

Have you drawn a free body diagram? Use that to find the net force, not F=ma.

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 'Collision of a bullet on a rod-string system: query'

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'A cylinder connected to a hanging mass'

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...
