A variable torque is applied to a rotating wheel attime t = 0 and causes the clockwise angular acceler-ation to increase linearly with the clockwise angulardisplacement 0 of the wheel during the next 30 revo-lutions. When the wheel has turned the additional30 revolutions, its angular velocity is 90 rad/s. Deter-mine its angular velocity wo at the start of the inter-val at t = 0.

In the image on the right, there is a red gear G1 on the left with a radius of r1 = 2.81cm. Gear G1 is locked to the green gear G2 with a radius of r2 = 0.734cm. Gear G2 then shares the same axle as the blue circular saw G3, which has a radius of r3 known to make a full rotation every T = 0.836s. Using at least 6 significant digits in your calculations, compute the following: V3! 12.8cm. Gear G1 is W1 a) The angular speed wi of gear G1. Remember that angular speed is measured in radians per T3 r2 unit time. G2 b) The rim speed vi of gear G1. Since gears G1 and G2 are locked together, the rim speed of G2 is also v1.
