Fluffy has just caught a mouse, and decides that the only decent thing to do is to bring it to the bedroom so that his human roommate can admire it when she wakes up. A constant horizontal force of 3.30 N is enough to drag the mouse across the rug at a constant speed v. If Fluffy's force does work at the rate of 6.30 W, what is her speed, v? How much work does Fluffy do in 4.50 s ?
