WebbAverage speed is a scalar, so we do not include direction in the answer. We can check the reasonableness of the answer by estimating: 5 meters divided by 2 seconds is 2.5 m/s. Since 2.5 m/s is close to 2.9 m/s, the answer is reasonable. This is about the speed of a brisk walk, so it also makes sense. Webbacceleration of falling body increases with time Volleyball players are taught to dive and roll when attempting to hit a low ball on the run. Explain the purpose of the roll in this dive …
