Question
The take-up reel of a cassette tape has an average radius of 1.4 cm. Find the length of tape (in meters) that passes around the reel in 13 s when the reel rotates at an average angular speed of 3.4 rad/s.
Step 1
We know that 1 cm = 0.01 m, so we multiply 1.4 cm by 0.01 to get the radius in meters. This gives us: \[ r = 1.4 \, \text{cm} \times 0.01 = 0.014 \, \text{m} \] Show more…
