Find the dimensions of
a. angular speed `omega`
angular acceleration `alpha`
torque `tau` and
d. moment of interia `I.
. Some of the equations involving these quantities are `omega=(theta_2-theta_1)/(t_2-t_1), alpha = (omega_2-omega_1)/(t_2-t_1), tau= F.r and I=mr^2`
The symbols have standard meanings.
