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...

Q6 (15 points): A Yo-Yo of mass m = 300 g has an axle of radius b = 1.5 cm and a spool of radius R 4 cm. The Yo-Yo is placed upright on a table and the string is pulled with a horizontal force F 8 N to the right as shown in the figure. If the Yo-Yo rolls without slipping, find its angular acceleration.

a yo yo of mass m and outer radius R rolls down a string on an axle of radius R0. The moment of inertia for the yoyo about its center of mass is Icm. Find the acceleration pf the yo-yo's center of mass ad it rolls down the string. draw as point particle.

A yo-yo can be modelled as a cylinder with radius r and mass m
(I = ½mr2). While hanging at the bottom of a string, the yo-yo is
given initial upward velocity and initial rotational velocity, and
as it moves upward the string is wrapped around the cylinder (for
simplicity, assume the string wraps around the full radius).
Determine the tension in the string as the yo-yo moves upward.

A spool of thread, free to unwind, is on a horizontal surface (with friction) and pulled directly upward (ty) a times. The spool rolls without slipping on the floor. The spool has a mass M, moment of inertia 1, and a radius of R. Assume the string is wrapped around the spool at a radius r (where r <R). 1) Which equation below is a correct expression of Newton's Second Law (XF- ma ) in the x (hortzontal) -direction for...

A string is wrapped around a uniform solid cylinder of radius r, as shown in the figure (Figure 1) . The cylinder can rotate freely about its axis. The loose end of the string is attached to a block. The block and cylinder each have mass m. Note that the positive y direction is downward and counterclockwise torques are positive. Find the magnitude α of the angular acceleration of the cylinder as the block descends. Express your answer in terms...

The car shown in the figure has mass m(this includes
the mass of the wheels). The wheels have radius r, mass
mw, and moment of inertia
I=kmwr2. Assume that the axles
apply the same torque ? to all four wheels. For
simplicity, also assume that the weight is distributed uniformly so
that all the wheels experience the same normal reaction from the
ground, and so the same frictional force.

If there is no slipping, a frictional force must...
