Keratinocytes are the most common cells in the skins outer layer. As these approximately circular cells migrate across a wound during the healing process, they roll in a way that reduces the frictional forces impeding their motion. (a) Given a cell body diameter of 1.00 105 m (10 m), what minimum angular speed would be required to produce the observed linear speed of 1.67 107 m/s (10 m/min)? (b) How many complete revolutions would be required for the cell to roll a distance of 5.00 103 m? (Because of slipping as the cells roll, averages of observed angular speeds and the number of complete revolutions are about three times these minimum values.)
A point on a rotating turntable 20.0 cm from the center accelerates from rest to a final speed of 0.700 m/s in 1.75 s. At t = 1.25 s, find the magnitude and direction of (a) the radial acceleration, (b) the tangential acceleration, and (c) the total acceleration of the point.
In Example 2.6, we considered a simple model for a rocket launched from the surface of the Earth. A better expression for the rockets position measured from the center of the Earth is given by y(t)=(R3/2+3g2Rt)2/3j where R is the radius of the Earth (6.38 106 m) and g is the constant acceleration of an object in free fall near the Earths surface (9.81 m/s2). a. Derive expressions for vy(t) and ay(t). b. Plot y(t), vy(t), and ay(t). (A spreadsheet program would be helpful.) c. When will the rocket be at y=4R? d. What are vy and ay when y=4R?
A pulley (in the form of a uniform disk) with mass Mp and radius Rp is attached to the ceiling in a uniform gravitational field g and rotates with no friction about its pivot. Mass M2 is larger than mass mı, and they are connected by a massless inextensible cord. T1, T2, and Ts are magnitudes of the tensions. What is the relationship between the ten- sion T and mi g?

A light, rigid rod is 75.5 cm long. Its top end is pivoted on a frictionless horizontal axle. The rod hangs straight down at rest with a small, massive ball attached to its bottom end. You strike the ball, suddenly giving it a horizontal velocity so that it swings around in a full circle. Wwhat minimum speed at the bottom is required to make the ball go over the top of the circle? m/s
One end of a cord is fixed and a small 0.550-kg object is attached to the other end, where it swings in a section of a vertical circle of radius 1.50 m, as shown in the figure below. When ? = 17.0°, the speed of the object is 6.00 m/s. At this instant, find the magnitude of the tension in the string.

A brick of mass 1.19 kg is attached to a thin (massless) cable and whirled around in a circle in a vertical plane. The circle has a radius of 1.34 m. The cable will break if the tension exceeds 45.0 Newtons. What is the maximum speed the brick can have at the bottom of the circle before the cable will break?
2. A conical pendulum consists of a 0.50 kg ball attached to a string with a length of 75.0 cm. The ball travels at a constant speed in a circle, while the string makes an angle of 32° with the vertical. What is the speed of the ball? I 324
A cylinder having a mass of 40 kg with the radius of 0.5 m is push to the right without rotation and with acceleration of 2 m/sec2. Determine the magnitude of the horizontal force P if the coefficient of friction is 0.30. * 40 kg a = 2 m/s ma 0.50 m F O P = 183 N O P = 198 N O P = 200 N O P = 232 N
A string under tension of 50.0 N is used to whirl a rock in a horizontal circle of radius 2.5 m at a speed of 20.4 m/s on a frictionless table. The string passes through a small hole in the table at the center of this circle. As the string is pulled in, the speed of the rock increases. When the string is 1.00 m long and the speed is 51.0 m/s, the string breaks. What is the breaking strength, in Newtons, of the string?
