ry - axis BEFORE Smooth Floor THE COLLISION (010 ) C M D = d DC - axis TV M > w AFTER THE 4-axis COLLISION M C M stops ge-axis A thin rod of mass M and of length d is lying at rest on a horizontal frictionless floor between x=0 and x=d. A point mass M moving with speed v along y-axis hits the rod at its one end at x=0. After hitting the rod the point mass stops. Please find the distance the center of mass c of the rod moves by the time the rod rotates by 90 degrees
