The figure shows an overhead view of a ring that can rotate about its center like a merry-go-round. Its outer radius R2 is 0.6 m, its inner radius R is R2/2, its mass Mis 7.4 kg, and the mass of the crossbars at its center is negligible. It initially rotates at an angular speed of 6.5 rad/s with a cat of mass m = M/4 on its outer edge, at radius R2. By how much does the cat increase the...

Figure 11-51 shows an overhead view of a ring that can rotate about its center like a merry-go-round. Its outer radius R2 is 0.8 m, its inner radius R1 is R2/2,its mass M is 8.8 kg, and the mass of the crossbars at its center is negligible. It initially rotates at an angular speed of 6.5 rad/s with a cat of mass m = M/4on its outer edge, at radius R2. By how much does the cat increase the kinetic...
Figure shows a uniform disk that can rotate around its center like a merry-go-round. The disk has a radius of 2.00 m and a mass of 20 kg and is initially at rest. Starting at time t = 0, two forces are to be applied tangentially to the rim as indicated, so that at time t=1.25 s the disk has an angular velocity of 250 rad/s counterclockwise. Force F1 has a magnitude of 0.100 N. What is magnitude F2? TE
The figure shows a uniform disk that can rotate around its center like a merry-go-round. The disk has a radius of 2.0 cm and a mass of 18 grams and is initially at rest. Starting at time t = 0, two forces are to be applied tangentially to the rim as indicated, so that at time t = 1.2 s the disk has an angular velocity of 300 rad/s counterclockwise. Force F1 has a magnitude of 0.101 N. What is...

Rotation Dynamics A uniform disk can rotate around its center like a merry-go-round. The disk has a radius of 2.00 cm and a mass of 20.0 grams and is initially at rest. The angular acceleration is 200 rad/s2counterclockwise. If F1 has a magnitude of 0.100 N, what is the magnitude of F2? 9. Fo
Consider the 13.0 kg motorcycle wheel shown in the figure. Assume it to be approximately an annular ring with an inner radius of R1 = 0.280 m and an outer radius of R2 = 0.300 m. The motorcycle is on its center stand, so that the wheel can spin freely. (a) If the drive chain exerts a force of 2190 N at a radius of 5.00 cm, what is the angular acceleration (in rad/s2) of the wheel? rad/s2 (b) What...
Consider the 15.0 kg motorcycle wheel shown in the figure. Assume it to be approximately an annular ring with an inner radius of R1 = 0.280 m and an outer radius of R2 = 0.300 m. The motorcycle is on its center stand, so that the wheel can spin freely. (a)If the drive chain exerts a force of 1800 N at a radius of 5.00 cm, what is the angular acceleration (in rad/s2) of the wheel? (b)What is the tangential...
