1. The problem statement, all variables and given/known data 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 2. Relevant equations i used a= change in v/t but did not get the correct answer 3. 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 ?
