Challenge Problems
Push your limits with advanced challenges
A spinning wheel speeds from 5 rad/s to 25 rad/s in 4 seconds. Calculate the angular acceleration, and discuss its physical significance in terms of motion.
💡 Hint: Use the defined formula and consider what forces would create this change.
A toy top spins steadily, then slows to a stop over 10 seconds due to friction. If its initial angular velocity was 30 rad/s, find its angular acceleration, and explain the implications of negative acceleration.
💡 Hint: Remember that negative acceleration implies the object is slowing down.
