Question

Please write legibly and write out all equations and units.

Please show all steps. Algebra-based physics only please.

I struggle with manipulating equations and keeping angular and linear variables separate.

1. When a bicycle is slowing down, the wheels slow with an angular acceleration of -15 rad/s2. If each wheel has a mass of 0.

12. Two solid rods, each which length L, radius R, and mass M, are connected together, as shown. When they are rotated around

20. A bicycle with 0.3 m radius wheel that the angular speed of each wheel is 75 rad/s. If the bicyclist then applies the bra

Answer #1

2 = -15 rad /s angular acceleration m = o.uky r=0.3m I = MR² = c.ux0.0g = 0.036 reg. m² Torque T = Id = 0.0364 (-15) T= -0.5= 0.3m , & win x = -15 rad 1st 75 rad/s , we o radls using with Wh + 220 (0)² = (75² – 2x 15 x 0 O = (75)2 = 5625 = 187.5 rad
