An T worker is setting up a new computer system for anadministrative assistant. She places a 12.5 kg laser printeron a desk and makes all necessary connectionsmove the printer to a location on the back, right corner of thedesk, she pushes it so that it has a constant velocity of 0 12m/s. If the printer moves 0.35 m what is the final time atwhich the printer is in place?n order to

Find the final time at which the printer should be placed.
