ASSIGNMENT # 5
1.
A
kicker’s extended leg is swung for 0.4 seconds in a counterclockwise direction
while accelerating at 299 deg/s2.
What is the angular velocity of the leg at the instant of contact with
the ball?
2.
The
angular velocity of a runner’s thigh changes from 3 rad/s to 2.7 rad/s during a
0.5 second time period. What was the
angular acceleration of the thigh? (Provide answer in both radians and
degrees).
3.
The
relative angle at the knee changes from 180 degree to 95 degrees during the
knee flexion phase of a squat exercise.
If 10 complete squats are performed, what is the total angular distance
and the total angular displacement undergone at the knee? (Provide answer in both radians and degrees)
