front view side view FT 1 R Ms Pulling the yo-yo [9pt] A non-intuitive motion that combines translation and rotation is pulling a wheel with a string wrapped around it, as shown in the figure above. Depending on what angle the string is pulled, you can obtain three kinds of motion: the yo-yo accelerating in the direction of the applied tension force and winding up, the yo-yo accelerating in the opposite direction of tension and unwinding, and the yo-yo sliding...

A yo-yo of mass m and radius R is placed on a horizontal surface as shown. A massless string is wrapped around an axle of radius r. The string will be pulled horizontally to the right as shown with a force of constant magnitude F. There is sufficient friction (f) between the surface and the yo-yo for the yo-yo to roll without slipping. Assume that the moment of inertia of the yo-yo about its rotation axis is approximatelyI (1/2)mR2. Draw...

Problem 4: A string is wrapped around a yo-yo which has r-12cm and mass of 350 gr and is at rest. A force of 5 N is applied to the right side of the yo-yo (where the string is) and points upwards as it is unwinding it. Imr/2 a) Find the angular acceleration of the yo-yo. b) Find the linear acceleration of all the points that are located at the circumference of the yo-yo e) Find the total angle it...

A yo-yo has a rotational inertia of 1100 g·cm2 and a mass of 118 g. Its axle radius is 1.99 mm, and its string is 133 cm long. The yo-yo rolls from rest down to the end of the string. (a) What is the magnitude of its linear acceleration? (b) How long does it take to reach the end of the string? As it reaches the end of the string, what are its (c) linear speed, (d) translational kinetic energy,...

D) You are playing Wheel of Fortune and pull down on the big uniform cylinder of mass M and radius R (take clockwise to be positive, as shown). You apply a constant force F to the edge of the wheel to spin for fortunes. Throughout your pulling on the wheel, you manage to keep the force perpendicular as it rotates. Assume that there is no friction anywhere and that the wheel is at rest before you start pulling. (i) Find...

Consider a uniform disk of radius R and mass m sliding down an incline making an angle θ with respect to the horizontal. The coefficient of kinetic friction between the disk and the surface is μk. The torque due to friction causes the disk to rotate as it slides down the incline. a) Compute the linear acceleration of the disk as it slides down the incline. b) Compute the angular acceleration of the disk as it slides down the incline....
