During the spin cycle of a top-loader washing machine, the clothes stick to the outer wall of the barrel as it spins at a rate as high as 1400 revolutions per minute (rpm). The radius of the barrel is 26 cm. (a) Draw a diagram of the situation from a bird’s eye view, indicating the tangential velocity and centripetal acceleration vectors at one time instant. (b) Calculate the tangential velocity of the clothes which are located on the wall of the spin barrel in m/s. (c) Calculate the centripetal acceleration of the clothes in m/s?.

A van with mass m = 1000 kg is driving around a circular curve of radius r = 950 m when it begins to rain. The coefficients of static friction between the track and tires is μd = 0.59 when dry and μw = 0.17 when wet. Write an expression for the maximum magnitude of the force of static friction Ff acting on the van if μs is the coefficient of friction. What is the maximum tangential speed that the van can take the corner at without slipping when dry in m/s? What is the maximum tangential speed when wet in m/s?

A manufacturer of CD-ROM drives claims that the player can spin the disc as frequently as 1100 revolutions per minute. If spinning at this rate, what is the speed of the middle row of data on the disc; this row is located 2.8 cm from the center of the disc?

Two Formula-one racing cars are negotiating a circular turn, and they have the same centripetal acceleration. However, the path of car A has a radius of 48 m, while that of car B is 37 m. Determine the ratio of the angular speed of car A to that of car B.
