Homework Statement
What is the linear velocity of the foot if the angular velocity of the dynamometer was 180 degrees/s and the distance from the knee joint to the foot is 0.5 m. Give your answer rounded to two decimal places in m.s-1. (Do not include units in answer).
Homework Equations
linear velocity = angular velocity (w) x radius (r).
linear velocity = w x r.
The Attempt at a Solution
w = 180 degree/s
r = 0.5m
linear velocity = ?
linear velocity = w x r
linear velocity = 180 x 0.5
linear velocity = 90 degrees/s
To find radians, 90/57.3 = 1.57 m/s
Is this correct? And in the right units?
Please help and thank you! :)
