    What is the linear velocity of a point on a swinging rod before it hits a wall?

    So, let's give this a shot. PE=mg(L/2)=5J Rotational KE=1/2*I*ώ2 I=1/3*M*L^2=1/3kg*m2 So solving for ώ gets me 5.46 rad/s which is the same in m/s because my L and radius is 1m. Does this seem right?

    What is the linear velocity of a point on a swinging rod before it hits a wall?

    Thanks for the quick reply. I'm having some trouble understanding this one. So my KE=1/2*I*W2. What would my W (angular velocity) be?

    What is the linear velocity of a point on a swinging rod before it hits a wall?

    Homework Statement If you suddenly cut the string, the rod will swing down. Find the linear velocity (V) of the point P just before the rod hits the wall (the momentum-of-inertial I=(1/3)ML^2 if the rod rotates about the end point Q. L is the rod length and M is the rod mass). The rod...
