Please answer question in 20 mintues of this question post. Thank you For the system shown, what is the critical angle α (the angle at which the system just begins to move)? Assume that the coefficient of friction between all flat surfaces is 0.06000 and that the pulley is frictionless and massless. The mass of m1=70.0 kg and m2=167 kg. Express the answer in radians.

In the setup shown in the figure, ?1=27.0kg, ?=220N, ?= 35°, and ?2=7.0kg. The frictionless pulley has a 0.1 m radius and its moment of inertia is 0.20 kg m^2. The coefficient of kinetic friction between ?1 and the table is 0.2. Calculate the acceleration of ?1.

The angular position as a function of time of a rotating cylinder is giving by: θ(t) = 2.50(rad/s2)t2 – 0.60(rad/s3)t3.  Find the maximum angular speed of the cylinder.  Use calculus. show full work when differentiating.

A thin- walled cylinder  of radius 50 cm, mass 1.0 kg, is mounted on a frictionless, horizontal axle as in Figure 1 . A light cord wrapped around the wheel supports an object of mass 2 kg. When the wheel is released, the object accelerates downward, the cord unwraps off the wheel, and the wheel rotates with an angular acceleration. Find the angular acceleration of the wheel, , and the tension in the cord.

As shown in the figure below, two blocks are connected by a string of negligible mass passing over a pulley of radius 0.350 m and moment of inertia I. The block on the frictionless incline is moving with a constant acceleration of magnitude a - 1.80 m/s². (Let m₂ = 14.5 kg, m₂ = 18.5 kg, and 8 = 37.0°) From this information, we wish to find the moment of inertia of the pulley. T₂ (a) What analysis model is appropriate for the blocks? O particle in equilibrium O particle under constant acceleration particle under constant speed particle under constant angular acceleration O particle in simple harmonic motion (b) What analysis model is appropriate for the pulley?

In the slider-crank mechanism, the slider block C is moving to the left with a linear velocity vc= 1.25 m/s. For the crank AB, find its corresponding angular velocity wAB at this instant. Given: a= 30 cm, b= 60 cm, 0= 30° and B= 53°. WAB a

HELP WITH THIS PLEASE, DO NOT DO b ONLY THE OTHER

Use at least 4 significant figures throughout the entire problem. 9.80m/s2 for the acceleration due to gravity. Do not use 10 m/s2 for the acceleration due to gravity.
