A handbrake is applied to a rotating wheel, initially moving counterclockwise, causing it to slow down with a constant angular acceleration of magnitude 5.20 rad/s2. Immediately after the handbrake is applied, the wheel rotates through 57.9 rad during a 4.00 s time interval. What is the angular speed (in rad/s) of the wheel at the end of this time interval?

(9%) Problem 3: A bicyclist notes that the pedal sprocket has a radius of rp = 9.5 cm while the wheel sprocket has a radius of rw = 6.5 cm. The two sprockets are connected by a chain which rotates without slipping. The bicycle wheel has a radius R = 64 cm. When pedaling the cyclist notes that the pedal rotates at one revolution every t= 1.4 s. When pedaling, the wheel sprocket and the wheel move at the same...
In the figure, point P is on the rim of a wheel of radius 2.0 m. At time t= 0, the wheel is at rest, and P is on the x-axis.
In the figure, point P is on the rim of a wheel of radius 2.0 m. At time t= 0, the wheel is at rest, and P is on the x-axis. The wheel undergoes a uniform counterclockwise angular acceleration of 0.010 rad/s2 about the center O. (a) what is the tangential acceleration of P? (b) What is the linear speed of P when it reaches the y-axis for the second time (hint, solve the angular speed first)? (d) How long after starting does...

ID: A 4. Consider the 13.0 kg motorcycle wheel shown in the figure. Assume it to be approximately an annular ring with an inner radius of RI -0.280 m and an outer radius of R2 = 0.320 m. The motorcycle is on its center stand, so that the wheel can spin freely. If the drive chain exerts a force of 2450 N at a radius of 5.00 cm, what is the angular acceleration (in rad/s2) of the wheel? a. 55...
