g) Describe the acceleration of the horse in the first 10 seconds. From the speed-time graph (Fig. 1.2), the speed of the horse increases from 0 m/s to 16 m/s in the first 10 seconds. The graph is a curve that becomes less steep over time. The gradient of a speed-time graph represents acceleration. Since the speed is increasing, the acceleration is positive. However, because the gradient of the curve is decreasing (the curve is flattening out), the rate at which the speed is increasing is slowing down. Therefore, the acceleration of the horse in the first 10 seconds is positive but decreasing. That's 2 down. 3 left today — send the next one.
