so if i am correct this is how u do it alpha=3 v=v0+at 0=15+3t -5=t

what is 'some kinematics'

what do u mean? Newtons law?

But the question says how long does it take for the yoyo to stop. The formula u provided is torque=I x alpha

Sois the formula alpha= moment of inertia times the force applies by the finger

i still don't get how to answer question c

sorry, for question c c) how ling does it take for the yo-yo to come to a stop its ment to be 'how long does it take for the yo-yo to come to a stop'

Homework Statement a yo-yo is spun from rest by pulling on the string with a constant tension of 2.0N. The radius of the inner rod on which the string is strung around is 0.50cm. the tension applied for 5.0seconds after which the yo-yo is observed to spin with an angular velocity of 15...

Homework Statement A ball of clay of mass m travels with velocity v in a path tangent to a disk of radius R and mass M. The clay collides with the disk tangentially to its outer rim ( a totally inelastic collision) and the clay and disk begins to spin about the axis. a) What is the final...
