Question 1
A fan blade is rotating at an angular speed of 30 rad/s. Calculate the linear speed of the tip of the blade, given its length is 0.25 meters.
💡 Hint: Remember to connect angular and linear velocities with the distance from the center.
Question 2
A wheel with a radius of 0.4 meters is rolling without slipping. If it rotates with an angular acceleration of 5 rad/s², what is the linear acceleration of the center of mass?
💡 Hint: Consider how rotational motion translates to linear motion.
