Problem a wheel rotates with a constant angular acceleration of 3.50 rad/s2. if the angular speed of the wheel is 2.00 rad/s at t = 0, (a) through what angle does the wheel rotate between t = 0 and t = 2.00 s? give your answer in radians and in revolutions. (b) what is the angular speed of the wheel at t = 2.00 s? (c) what angular displacement (in revolutions) results while the angular speed found in part (b) doubles? strategy the angular acceleration is constant, so this problem just requires substituting given values into the proper equations. solution

11 radians or 1.7507 revolutions

9 rad/s

7.27565 revolutions

Explanation:

= Final angular velocity

= Initial angular velocity

= Angular acceleration

= Angle of rotation

t = Time taken

Equation of rotational motion

Angle the wheel rotates in the given time is 11 radians or 1.7507 revolutions

The angular speed of the wheel at the given time is 9 rad/s

The number of revolutions if the final angular speed doubles is 7.27565 revolutions

the answer is neither ball has a charge.

because if they were both positively charged, they will repel each other.

if they were positively and negatively charged, they will seek.
