Explanation / Answer

(a) angular speed = speed /radius = 48.983 rad/s (b) angular acceleration = tangential acceleration /radius = a/R =        now, * =2       = 48.983, =2, => = 190.933 rad/s2 = /2rev/s2 = 30.388 rev/s2       at = R* = 30.388*0.794 m/s2 =24.128 m/s2       radial acceleration = v*v/R =3021.832 m/s2 (c) F = m*a        tangential force = M*at =4.777 N        Radial force = M*v*v/R =598.323 N
