Please help Points: 10 12) A 18 kg solid disk pulley of radius 0.11 m rotates about an axis through its center (a) What is its moment of inertia? (b) Starting from rest, a torque of 0.22 m-N will produce what angular acceleration? FIGURE 8-5 13) A solid disk with diameter 2.00 meters and mass 4.0 kg freely rotates about a vertical axis at 36.rpm. A 0.50 kg hunk of bubblegum is dropped onto the disk and sticks to the...
Page 13 9. A 49.8-kg athlete running at 4.54 m/s suddenly jumps onto a stationary playground merry-go-round at a distance 1.45 m from the axis of rotation of the merry-go-round. She is traveling tangential to the edge of the merry-go-round just before jumping on. The moment of inertia about its axis of rotation is 625 kg m2 and very little friction at its rotation axis. What is the angular speed of the merry-go-round just after she has jumped onto it?...
please draw a picture Q.3 A solid disk with a mass of 36 kg and a radius of 0.7 m is spinning around an axis through its center, it rotates with an angular speed of 3 full turns per second. You drop a 12 kg mass onto the disk at the edge, it sticks to the disk, reducing the angular speed to ws. Next you apply a 30 N force tangentially at the edge of the disk to slow it...
A solid disk rotates in the horizontal plane at an angular velocity of 0.0612 rad/s with respect to an axis perpendicular to the disk at its center. The moment of inertia of the disk is 0.134 kg·m2. From above, sand is dropped straight down onto this rotating disk, so that a thin uniform ring of sand is formed at a distance of 0.398 m from the axis. The sand in the ring has a mass of 0.509 kg. After all...
A solid disk rotates in the horizontal plane at an angular velocity of 0.0647 rad/s with respect to an axis perpendicular to the disk at its center. The moment of inertia of the disk is 0.199 kg·m2. From above, sand is dropped straight down onto this rotating disk, so that a thin uniform ring of sand is formed at a distance of 0.420 m from the axis. The sand in the ring has a mass of 0.499 kg. After all...
A solid disk rotates in the horizontal plane at an angular velocity of 5.00 × 10-2 rad/s with respect to an axis perpendicular to the disk at its center. The moment of inertia of the disk is 0.15 kg.m2. From above, sand is dropped straight down onto this rotating disk, so that a thin uniform ring of sand is formed at a distance of 0.40 m from the axis. The sand in the ring has a mass of 0.50 kg....
can someone help me solve 5-7 5. Two particles of mass 1 kg each are attached to a massless rod a distance of 1 m and 2 m respectively from the axis of rotation. The axis of rotation is perpendicular to the rod. The angular speed of the system is I rad/s. What is the magnitude of the angular momentum of the system (in SI units)? 1kg - 1kg 1 m 2 m Lamur 3 A1 B. 4 1.1.2 Homes...
please help with number 6! YouTube Apps Maps G Gmail Cakc Help Tec Com research intership app Turntable 7 A horizontal turntable is made from a uniform sold disk and is initially rotating with angular velocity of 8.7 rad/s about a fixed vertical axis through its center. The turntable has a radkus of 0.2 m and a moment of inertia of 0.034 kg m about the rotation axis. A plece of clay, Initially at rest, is dropped onto the turntable...
Thanks so much for the help! Please show all work. A uniform solid disk with radius 9 cm has mass 0.5 kg (moment of inertia I = ½MR2). A constant force 12 N is applied as shown. At the instant shown, the angular velocity of the disk is 40 radians/s in the −z direction (where +x is to the right, +y is up, and +z is out of the page, toward you). The length of the string d is 13...
hi. i am stuck. please help with all of these. thank you A potter's wheel, with rotational inertia 21 kg.m2, is spinning freely at 40 rpm. The potter drops a lump of clay onto the wheel, where it sticks a distance 1.2 m from the rotational axis. If the subsequent angular speed of the wheel and clay is 32 rpm what is the mass of the clay? 3.1 kg 4.3 kg 2.4 kg 4.0 kg 3.6 kg The simple harmonic...
