# The graph above shows the angular velocity of a spinning wheel (radius = \( 25 \) \( \text{cm} \)) as a function of time.

The graph above shows the angular velocity of a spinning wheel (radius = \( 25 \) \( \text{cm} \)) as a function of time.

**Part a)** What is the angular acceleration of the spinning wheel at \( t = 4 \) seconds? *(1 points)*

**Part b)** What is the speed of a point on the rim of the wheel at \( t = 1 \) second? *(1 points)*

**Part c)** What is the angular displacement of the wheel in the first \( 2 \) seconds? *(1 points)*

**Part d)** What is the angular displacement of the wheel from \( 2 \) to \( 4 \) seconds? *(1 points)*

**Part e)** What is the total angular displacement of the wheel from \( 0 \) to \( 10 \) seconds? *(1 points)*

**Part f)** The wheel rolls along level ground. What is its total displacement after \( 10 \) seconds? *(1 points)*

**Part g)** What is the magnitude of the tangential acceleration of a point on the rim at \( t = 4 \) seconds? *(1 points)*

**Part h)** What were the tangential and centripetal accelerations of a point on the rim at \( t = 1 \) second? *(1 points)*
