Challenge Problems
Push your limits with challenges.
Question 1
A merry-go-round is rotating at an angular velocity of 2 rad/s. If it accelerates at a rate of 0.5 rad/sΒ², calculate how long it will take to reach an angular velocity of 6 rad/s.
π‘ Hint: Rearranging the formula can help solve for time.
Question 2
A basketball player spins around while dribbling, increasing her rotation speed at 1.5 rad/sΒ². If she starts from rest, what is her angular velocity after 4 seconds?
π‘ Hint: Calculate the final velocity using the acceleration over time.
