A mass is tied to a string and whirled in a vertical circle. Categorize the following according to whether they are 0 in value, constant in value, or change: a: linear acceleration (scalar) a linear acceleration (vector) a: radial (centripetal) acceleration (scalar) a: radial acceleration (vector) v. linear speed v. linear velocity o angular acceleration (scalar) w angular speed constant and 0 constant and non-zero non-constant linear acceleration (scalar) radial acceleration (scalar) linear speed angular speed linear acceleration (vector) angular acceleration (scalar) radial acceleration (vector) linear velocity An ultracentrifuge accelerates from rest to 981000 rpm in 1.87 min. What is its angular acceleration in rad / s²? Number What is the tangential acceleration of a point 8.90 cm from the axis of rotation? Number rad/s² Number m/s² What is the radial acceleration in m/s² and multiples of g of this point at full rpm? m/s² Number An optical disk drive in your computer can spin a disk up to 10,000 rpm (about 1045 rad / s). If a particular disk is spun at 235.6 rad /s while it is being read, and then is allowed to come to rest over 0.502 seconds, what is the magnitude of the average angular acceleration of the disk? Number rad/s² If the disk is 0.12 m in diameter, what is the magnitude of the tangential acceleration of a point 1/8 of the way out from the center of the disk?
