Question

ca-6
answer is a

m/s as shown below in the figure t masses are rotating on a light turntable with a speed of 1.20 labeled "Before". The masses slide out to the edge of the turntable while the turntable is rotating freely (no torques are exerted on the turntable). See the figure below labeled "After". Use this information to answer problems CA-5 thru CA-7. Show your work for each part. CA-5 Find the total angular momentum in S.I. units Before: 0.0800m After: 0.4 of the two 15 kg masses before sliding. a. 2.88 b. 36.0 c. 353 d. 450 CA-6 Find the total angular momentum in S.I. units of the two 15.0kg masses after sliding. a. 2.88 b. 14.4 c. 90 d. 353 e. 450 CA-7 Find the speed in m/s of the 15.0kg masses after sliding. a. 0.24 b. 1.20 c. 7.50 d. 29.4 e. 37.5

Explanation / Answer

Since therse is not any torque is acting hence its angular momentum will be conserved

5. L = 2*M*V0*R0 = 2*15*1.2*0.08 = 2.88 Kgm2s-1 6.Since angular momentum is conserved henceinitial angular momentum = final angular momentum = 2.88Kgm2s-1

7. 2*M*V1*R1 = 2.88

V1 = 0.24 m/s
