Practice 1. What is the centripetal acceleration of a locomotive that travels around a circular curve of radius 250 m at a constant speed of 70 both? {1.5 rots?) . What is the centripetal acceleration of a small girl standing at the outer edge of a carousel 4.0 m in diameter, which makes one complete rotation in 6.0 s? [2.2 meE) . Patrons on the midway ride called the Enter stand with their backs against the wall of a revolving cylinder, while the oor drops away from beneath them. To keep from failing, they require a centripetal acceleration of about 25 mish If the norm has a diameter of 5.0 m. with what minimum frequency does it revolve? [The vertical force required to support their weight is supplied by friction with the wall} [0.50 Hz} Art airplane ies in a horizontal circle of radius SOD m. Ii its centripetal acceleration is 20 lTlsz, how long does it take to complete the circle? [31 s)
