(use block-surface as the system) Alice applies a constant Force F of 15.0 N directed at 40 degrees below the horizontal on a crate moving on a rough horizontal flat surface. The mass of the crate is 4.00 kg. With her force, she continues to slide the crate from A to B for a distance of 20 m, where it reaches a speed of 11.5 m/s. Determine the speed (m/s) of the block at A if the internal energy of the system increases by 95.5 J as the block moves from A to B.
