Answer #1

if we had a uniform bar floating in space and force F is applied at one end perpendicularly ,

if we applied force F at one end of the rod , then according to newton's second law

FY = m acm { FY = force in Y direction perpendicular to bar }

the force acting only Y direction , so acceleration , acm = F/m .so the rod purely translates as whole and it does not rotates.there is no external torque is acting because the end of the rod accelerating linearly along with the center of mass of bar.

On a frictionless table, a 0.62 kg glob of clay strikes a uniform 1.12 kg bar perpendicularly at a point 0.21 m from the center of the bar and sticks to it. If the bar is 1.34 m long and the clay is moving at 7.50 m/s before striking the bar, what is the final speed of the center of mass? At what angular speed does the bar/clay system rotate about its center of mass after the impact?
