What Is the Acceleration of an Object on a 78-Degree Inclined Plane?

AI Thread Summary
To determine the acceleration of an object on a 78-degree frictionless inclined plane, it is essential to apply Newton's Second Law and analyze the forces acting on the object. The gravitational force can be resolved into components parallel and perpendicular to the incline. A free body diagram is recommended to visualize these forces and their directions. The acceleration can be calculated using the formula a = g * sin(θ), where g is the acceleration due to gravity. Understanding these concepts is crucial for solving the problem effectively.

Frictionless incline plane homework help!

Homework Statement



An object is on a frictionless inclined plane. The plane is inclined at an angle of 78.0 degrees with the horizontal. Using the accerlation due gravity from your reference table. What is the magnitude of object's acceleration?

Homework Equations


a= delta v/ t or g=F^g/ m or vf=vi+at or d= vit+1/2at^2 or vf^2=vi^2+2ad


The Attempt at a Solution


a= delta v/ t

Hi inedhelpinphy, welcome to PF!:smile:

Draw a picture!:wink:...What forces (there is more than one!) act on the object? What are their magnitudes and direction? What is the magnitude and direction of the net force on the object? What does Newton's second law tell you?
 

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...
