Please Use algebra not calculus to answer the following: The picture shows a view from above of a non-uniform object (a rectangular slab with objects placed on it) dropped onto a platform rotating on a low-friction bearing. The mass of the rotating disk is 2.85 kg. 1. Show a Force Diagram 2. Make measurements and calculations to determine the rotational inertia of the slab (including the objects on the slab). Explain your process and results. (Please use the given diagrams to find the rotational inertia) 3. Describe the major assumptions you made during your process. 4. Do you think the actual value of the rotational inertia of the slab (with the objects on it) is more likely to be greater than your value, or less than your value? Support your assertion.
A car starts from rest and in 75 seconds it travels 1 mile. The wheels of the car have a diameter of 30 inches. Show all work and any unit conversions step by step. a) How many revolutions did the wheel make in that 1 mile distance?b) What was the final linear velocity of the car after the 75 seconds in units of feet per second?c) What was the final angular velocity of a point on the outer edge of the wheels in units of rpm?
A rotating object has an angular position represented by θ=A+Bt+Ct2 , where A , B , and C are constants. A student wants to represent a different rotating object that has twice the angular speed at every moment. To write the new function, the student could
Fred examines the range of motion of Oscar’s knee joint during rehabilitation from a knee injury. At full extension, the angle between the lower leg and thigh is 178°. At full flexion, the angle between the lower leg and thigh is 82°. During the test, Oscar’s thigh was held in a fixed position and only the lower leg moved. What was the angular displacement of Oscar’s leg from fullextension to full flexion? Express your answer in (a) degrees and (b) radians.
Below is a sketch of the toy on a rotor ride at the moment after the floor drops. The rotor has a radius of R and the toy has mass m. Assume the angular velocity is constant, and the toy is not slipping downward. write Newton’s Second Law for the x and y directions. Use algebra and your equations above to predict the minimum angular velocity ωmin necessary to keep the toy “stuck” to the side of the rotation tube. Express your answer in terms of g, μs, R. (nonumbers yet). Show all of your work and your final result below.
A disk drive with a radius of 0.065 m starts rotating from rest with a constant angular acceleration. It takes 2.5 seconds to complete ten revolutions. One complete revolution takes how long? What is the linear displacement of the rim after ten revolutions? Determine the angular acceleration of the disk in radians per second squared (rad/s^2). Please provide work so I may better understand, thank you.
I am trying to find the final angular velocity of a cylinder after you throw a ball at it. The knowns are shown in the images that will show the context of the problem. The value I have already solved for is the angular velocity after disk 1 is dropped on disk 2 which is -6.7697 rad/s, the other value is the change in thermal energy created from the collision which is 5258.629 J. thanks.

Answer the following questions. Explain your answers and explain by drawing (True or False) c) A wheel of radius r is rolling while slipping at the point of contact between the wheeland ground.The speed of the wheel's center is v = rω.
The topic is all about the Angular Motion of Particles. Please use pen and paper to solve and also use three decimal places. Please show the conversion solution. Thank you. Here are the formulas: θ=θ_o+ω_o t+1/2 αt^2 ω=ω_0+αt ω^2=ω_o^2+2α(θ-θ_o) considering the tangential and normal components of the acceleration in a curvilinear motion of particles: a_t=rα a_n=rω^2=vω The angular motion may be derived from the translational motion of particles by considering the given circle: s=rθ ds/dt=r dθ/dt or v=rω dv/dt=r dω/dt or a=rα
Two big bugs, Buzz and Crunchy each of mass 0.65 kg, are siting on a spinning disk on a horizontal plane. Buzz is sitting halfway and Crunchy is sitting at the outer edge as shown. The radius of the disk is 7.2 m and it rotates once every 1.2 s. What is the magnitude of the net force on Buzz, in Newtons? Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.
Just explain concepts, formulas, theories as if you were to solve.... A hoop and a solid disk both have the same radius and mass and negligible thickness. Assume that they are both rotating with the same constant angular speed. Which has the higher rotational kinetic energy? If you see an object rotating, is there necessarily a net nonzero torque acting on it? Why or why not? A skater rotates quickly on the ice. He pushes his arms out. What happens to his angular speed? Why? A 100 gram meter stick has a wad of clay on one end of it. The stick is supported from a fulcrum point 33 1/3 cm from the clay. What is the clay's mass? A student sits on a rotating stool holding two 3.0 kg objects. When his arms are extended horizontally, the objects are 1.0 m from the axis of rotation and he rotates with an angular speed of 0.75 rad/s. The moment of inertia of the student plus stool is 3.0 kg m2 and is assumed to be constant. The student then pulls in the objects horizontally to 0.30 m…
