Homework Statement
The canister of a juicer has 333 grams of pulp distributed over its inside wall at an average radius of 8.00cm. It starts from rest and reaches its maximum angular speed of 3600.0 rpm in 4.00 seconds. For the pulp, determine ( f ) the tangential and centripetal force on it at t = 2.00s and t = 4.00s. my question why tangential force is constant and centripetal force is varying?
Homework Equations
tangential force F=ma =m ∝ r
centripetal force= mv²/r
3. The Attempt at a Solution
Ft = Mat ; ( Ft )1 = ( 0.333 kg )( 7.54 m/s2 ) = 2.51 N ; ( Ft )2 = 2.51 N (Constant tangential force)
Fc = Mac ; ( Fc )1 = ( 0.333 kg )( 2850 m/s2) = 949 N
( Fc )2 = ( 0.333 kg )( 11400 m/s2) = 3800 N ( Variable centripetal force)
