Finding intial velocity given vertical and horizontal displacement

AI Thread Summary
To find the initial velocity given horizontal and vertical displacements, key equations include the kinematic equations for projectile motion. The horizontal displacement remains constant, while the vertical displacement is influenced by gravity. It's important to resolve the initial velocity into its horizontal and vertical components based on the launch angle. The discussion also raises questions about the units for displacements and the specific kinematic equations needed for calculations. Understanding these concepts is crucial for solving the problem effectively.

what is the initial velocity when:
Horizontal displacement= 1.51
Vertical displacement= -.273
angle launched= 36

could someone at least tell me the equations i need to use, because i am totally lost

Is there any units for the displacements.
Do you know, how to resolve the velocity into vertical and horizontal components?
Out of this, which component remains constant?
What are the kinematic equations?
 

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'

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...
