A roller coaster car accelerates from a stop to 25 m/s as it descends a slope in 10 seconds. Calculate the angular acceleration if the radius of the track is 5 meters.
💡 Hint: Remember that linear velocity translates into angular when considering the radius.
A wheel rotates with an initial angular velocity of 12 rad/s and decreases to 6 rad/s over 4 seconds. Determine the angular deceleration.
💡 Hint: Review the formula and the signs of angular velocities.
