## Homework Statement

The absolute angle of the thigh has the following angular velocities during the support phase of

walking. Calculate the angular acceleration at time 0.02s in rad/s and in deg/s

Time (s) Angular Velocity (rad/s)

0 s ---- 1.033

0.02s ------ 1.511

0.04s ----- 1.882

0.06s -----2.19

## Homework Equations

i used a= change in v/t but did not get the correct answer

## The Attempt at a Solution

i subtracted the final velocity from the velocity at 0.02 and did the same with time. so i got 0.679/0.04 but my answer is off. what am i doing wrong ?
