Question

Part A - Practice Problem: In this example we will apply the equations for constant angular acceleration to the simple case of a rotating bicycle wheel. The angular velocity of the rear wheel of a stationary exercise bike is Wo = 4.00rad/s at time t=0, and its angular acceleration is constant and equal to a = 2.50rad/s". A particular spoke coincides with the + axis at time t=0 (Figure 1). What angle does this spoke make with the ads at time t = 3.00s? What is the wheel's angular velocity at this time? How much longer will it take before the reference spoke is once again al Express your answer in seconds to three significant figures.

Practice Problem: O for chosen spoke What will the angular speed of the wheel be at this time? Express your answer in radians per second to three significant figures. Ηθο ΑΣΦ 6 * Ο ? 6.87

Answer 1

augh made by spoke at t-3.00s - 0= wat t l at ² - = 4x3 + 1x2 50x32 La 23:25 angular speed, w = watat = 4 +(9.5103) 2 = 17:50 rool I sec.

Dear bloke,

I didn't able to read your part a that's why not answered. Post it again. However i have answered two parts asked. Please rate up bro.

Thanks and have a good day ahead of your semesters.
