I also agree with that ^^

There are some hint in the questions. It asked that why we hv to increase the angular speed of the tape to a maximum value, and how does it releate to the value of b?

Thank you for your answer But sorry, I don't quite understand the meaning of " What function of t?" ><

My work: Fc= mrω2 Mg= mL4∏2 / (t/20)2 = 1600mL∏2 / t2 And I don't know why there are a and b :(

It is given ><

It's an experiment to verify centripetal acceleration= rω2 Producedures: 1. Set up the apparatus as shown in the photo. 2.Hold the plastic tube vertically and whirl the sticky tape above your head in a horizontial circle.Increase the angular speedof the sticky tape to a maximum value such...

Mg=[1600∏2m(L+a)(1/t2)]- b M is the mass of the slotted weight g is the gravitational force m is the mass of the sticky tape L is the length of the nylon thread measured from the end of the plastic tube to the sticky tape t is the time for 20 revolutions of the sticky tape a and b are...
