Calculating Angular Velocity and Angle on a Game Show Wheel

AI Thread Summary
To calculate the angular velocity and angle of the game show wheel, the initial angular speed is 3.70 rad/s, and the wheel rotates through 1.25 revolutions before stopping at the BANKRUPT space. The problem requires determining the angle when the angular speed is reduced to 1.50 rad/s, assuming constant angular acceleration. To solve this, one must first calculate the angular acceleration using kinematic equations. This approach is essential for accurately determining the wheel's motion dynamics.

Angular velocity HELP!

On a certain game show, contestants spin a wheel when it is their turn. One contestant gives the wheel an initial angular speed of 3.70 rad/s. It then rotates through one-and-one-quarter revolutions and comes to rest on the BANKRUPT space. Through what angle has the wheel turned when its angular speed is 1.50 rad/s?


?? rad

Help Please I suck as this stuff
 
Physics news on Phys.org
Hint: Assume the angular acceleration is constant and treat this as a kinematics exercise. First figure out the acceleration.
 
OKKKKK Thanx a lot that help
 

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...
