Jessica pulls her sister Katie in a wagon. The wagon and Katie together have a mass of 28.5 kg. Jessica starts up a 98.0-m-long slope that is 4.5 m high. On the slope, Jessica pulls on the wagon with a constant force of 9.0 N. They start out at the bottom of the slope with a speed of 5.8 m/s. What is their speed at the top of the slope?
