Answer:
a) For this case we want to find the acceleration of the bowling ball, and we now that the only acceleration for this case would be the centrifugal acceleration becuase since the pendulum is in phase with the equilibrium point the tangential acceleration is 0, and if we find the centrifugal acceleration we got:
b) For this case the tendsion is an opposite force against the weight and the centrifugal force acting in the ball so then we can find the tension like this:
In order to find the mass we know that and solving for m we got:
And replacing into the tension we got:
Explanation:
For this case we have the following data given:
represent the weigth for the object
the length of the rope or the radius
represent the velocity of the bowling ball
Part a
For this case we want to find the acceleration of the bowling ball, and we now that the only acceleration for this case would be the centrifugal acceleration becuase since the pendulum is in phase with the equilibrium point the tangential acceleration is 0, and if we find the centrifugal acceleration we got:
Part b
For this case the tendsion is an opposite force against the weight and the centrifugal force acting in the ball so then we can find the tension like this:
