When a father takes his daughter out for a spin in a stroller, he exerts a force F>with a magnitude of 44.0 N at an angleof 32.0° below the horizontal, as shown in the sketch. The stroller and child together have a mass m = 22.7 kg. (a) Howmuch work does the father do on the stroller when he pushes it through a horizontal distance d = 1.13 m? (b) If theinitial speed of the stroller is vi = 1.37 m>s, what is its final speed? (Assume the stroller rolls with negligible friction.)
