When spinning a coin on a flat surface, two equal forces with opposite directions are applied
to the opposite sides of a coin. Which of the following is true about the coin after it leaves
the hand? (Assume ideal frictionless motion)

b. The coin does not rotate because equal but opposite torques cancel each other out
c. The coin rotates and the rotational acceleration is zero
d. The coin rotates and the rotational acceleration is equal to the nonzero net torque divided
by the moment of inertia - **🔰 VERIFIED ANSWERS🔰 ✔✔C
