The pulley rotates without friction. initial condition at rest R (in m/s^2) I VILA m The moment of inertia of the pulley is I. Calculate the acceleration of the block when the pulley begins to rotate. DATA: m = 13 kg; R = 1.0 m; I = λm R²; λ = 0.55; OA: 1.143 OB: 1.521 OC: 2.023 OD: 2.690 OE: 3.578 OF: 4.759 OG: 6.329 OH: 8.418

The answer is supposed to be v=2.56m/s but I'm not sure how to write out the problem.

F Pivot d The length of the pool cue is 1.5 m. A force of 11 N is applied at an angle 55°, a distance 0.7 meters from the pivot. What is the torque created? Answer to 3 sig figs.

Two masses, m₁ = 31.0 kg and mp = 42.0 kg are connected by a rope that hangs over a pulley (as in the figure(Figure 1)). The pulley is a uniform cylinder of radius R = 0.316 m and mass 3.3 kg. Initially, mis on the ground and mp rests 2.5 m above the ground. igure MA MB 4 2.5 m 1 of 1 Part A If the system is now released, use conservation of energy to determine the speed of mp just before it strikes the ground. Assume the pulley is frictionless. Express your answer using three significant figures and include the appropriate units.

Answer the following question You are given four objects. A Solid cylinder, a thin-walled hollow cylinder, a solid sphere, and a hollow sphere. All of them have the same mass ?m, and radius ?R. They are all put on an incline plane of hight ℎh, and angle ?θ. 1a) Derive a formula for the final speed at the bottom of the ramp in terms of ?,?,ℎ,?m,R,h,I, and ?θ. 1b) Which one will get to the bottom first? (Hint: ?I is for Rotational Inertia).

Crank OA is rotating at a counterclockwise angular rate of 9.4 rad/s, and this rate is decreasing at 4.3 rad/s². Determine the angular acceleration AB of link AB for the position shown. The angular acceleration AB is positive if counterclockwise, negative if clockwise. 100 mm 9.4 rad/s 85 mm Answer: CAB= 38° G AB=210 mm B rad/s²
