A ball starts from rest and rolls down a steep slope. The ball then rolls along rough horizontal ground. Which graph shows the speed of the ball at different times?

1. Aspeed-time graph: speed increases from zero then becomes constant
2. Bspeed-time graph: speed constant then decreases to zero
3. Cspeed-time graph: speed increases then drops sharply to zero
4. Dspeed-time graph: speed increases then gradually decreases
