1. The problem statement, all variables and given/known data The following data are for the angular displacement of the knee in cycling measured in degrees. Using radian measure, compute the angular velocity and acceleration when the knee angle is 119.1 degrees. The sampling frequency was 50 Hz. What is a problem you may encounter when calculating higher derivatives from sampled displacement data? 98.0, 103.5, 109.0, 114.2, 119.1, 123.4, 126.9 2. Relevant equations Angular velocity is degrees per unit time. 3. The attempt at a solution I only have the angle. And a frequency but not a discrete time variable? Thanks!
