B. The direction Velocity is a vector quantity such that it has magnitude which is the scalar component and direction as well. In this case, though magnitude is known but direction of her speed is not known. Hence, we cannot calculate correct velocity.
Veronica’s velocity was measured as 4.3 m/s. She displaced 20 meters in 4.7 seconds. Which piece of information is missing for the correct calculation of velocity? A) the starting point B) the direction C) the end point D) the time per meter
