(r,(e) 2. Click "Reset All" again and this time drag the Beetle on the turntable and put it at (3,0). Set the angular velocity of 100 degrees/s. Now click "Go" and stop it after the turntable rotates twice. Make sure you did click on 0,00,v graph to answer the following questions What are the values you read after it completes its rotation? Ladybug: 0= 720.8 a. 3.49 m/s degree. = 100 degrees/s, Beetle: 0110. degree, = 100 degrees/s, b. Click on "radians" and write the values you read Ladybug: 0= 12.58 rad, @=1.75 rad/s, AR = V² R Beetle: 0= 12.57 rad, @= 1.75 rad/s, c. What are the angular and centripetal accelerations Ladybug: ag 6.09 m/s², a= rad/s² Beetle: ag 9.12 m/s², a= rad/s² V= v=5.23 m/s v = 3.49 m/s v=5.23 m/s 3.492 2 5.232 3
dimension" simulation. In this simulation we are dealing with rotational kinematics. If the motion is pure rotation, the equations can easily be rewritten by changing the translational symbols to rotational. The symbols and the rotational kinematics equations are given below. @=d0/dt do/dt α = @= 40/At a = 400/At Displacement Velocity Acceleration Translational X R V a Angular 0 as (0) a x=OR VOOR ataR 0= 0 + (t-to) @= a + a(t-to) a= a + 2(x-xo) 0 = 0 + 0 (t-to) + 2(t-to)² Angular displacement: units used for angle are degrees and radians. Linear quantities can be related to angular quantities as shown in the table to the left. dangular acceleration w = angular velocity As you see the figure on the left, the ladybug is located R from the center of axis of rotation. Its tangential velocity (v.), tangential acceleration (a), centripetal acceleration (as), and combined (resultant) acceleration (a) are specified. The equation for centripetal and combined accelerations are given by v2 aR R a = |a² + a²
