**Henry**, Thursday, November 10, 2011 at 9:58pma. C = pi*D = 3.14 * 2.45 = 7.7m.

V=74.1rev/min * 6.28rad/rev *(1/60min/s

= 7.76 rad/s.

b. V = 7.76rad/s * 7.7m/6.28rad=9.51m/s

c. t = 102s / 60s/min = 1.7 min.

V = Vo + at = 1260rev/min.

74.1 + 1.7a = 1260,

1.7a = 1260 - 74.1 = 1185.9,

a = 698rev/min^2.

d. rev = 1260rev/min * 1.7min = 2142
