Circular Motion: Centripetal Force & Acceleration, Linear & Angular Velocity // HSC Physics

[@ScienceReady]

There's a mistake at 14:46 - the radius should be 2 m, not 5 m. This would give you a speed of 62.8 m/s.

yeaahh i noticed that!! I used omega = 2pi * frequency and velocity = radius * omega First of all I solved for omega which was like: omega = 2pi * 5 omega = 10pi and then the velocity, the radius was 2 and i did 10pi*2 = 20pi (which is 62.8 m/s) and i was a bit confused until i saw your comment haha

i saw that the force for that question was 6190 how did you get that?

[@carbonatedsuaceyt4124]

@@PCRGaming722 right, when i did it i got 6162250

[@cher8693]

so the centripetal force would be 986960.4... N ??

[@malcolmy]

Yes, I noticed it and found 986960.4 as answer
