WebFeb 13, 2024 · Multiply the acceleration by time to obtain the velocity change: velocity change = 6.95 × 4 = 27.8 m/s. Since the initial velocity was zero, the final velocity is … WebAverage 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. WebYour notion of velocity is probably similar to its scientific definition.
