    Angle Velocity
AI Thread Summary
To solve for the necessary velocity when given horizontal and vertical distances along with an angle, one can utilize basic kinematic equations. The vertical motion can be described by the equation v[y] = v.sin(p).t - 0.5gt^2, while the horizontal motion is represented by v[x] = v.cos(p).t. By rearranging these equations, the unknown variables can be solved systematically. This approach allows for the calculation of the required velocity to clear the specified distances at the given angle. Understanding these equations is crucial for accurately determining the necessary velocity in projectile motion scenarios.

how do i solve for the necessary velocity when the horizontal and vertical distances to be cleared are given and there is an angle involved?

thank you

thank you

use those simple kinematics equations, and solve the unknown vars!

v[y] = v.sin(p).t-0.5gt^2
v[x] = v.cos(p).t
 

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...
