Question

A rock tied to the end of string swings at a constant angular rate. You measure the rock to pass through 6 π radians in 4.20 seconds. If the length of the string 0.40 meters in length, what is the linear tangential velocity of the rock? Give your answer in units of meters per second. Note: Give only your numerical answer. Do not include units, else your answer will be incorrectly scored.

Step 1

Angular velocity is defined as the rate of change of angular displacement and it is equal to the total angle traversed divided by the time taken. So, the angular velocity (ω) = total angle traversed / time taken = 6π radians / 4.20 seconds = 1.5π rad/s. Show more…
