A'Zorria Ward An elevator traveled 15 floors (150 ft) at a speed of 4.5 m/s. What additional information is needed to determine the velocity of the elevator?
the direction the elevator traveled
how long the elevator was stationary
O how many times the elevator stopped
O the total mass of the elevator plus anything in it

Explanation:

An elevator traveled 150 ft at a speed of 4.5 m/s. What additional information is needed to determine the velocity of the elevator?

Velocity is vector quantity.So it needs direction in addoition to speed.

The velocity of an object is the rate of change of its position with respect to a frame of reference, and is a function of time. Velocity is equivalent to a specification of its speed and direction of motion.

idk i’m struggling too

practical process described pest part of scientific investigation.

because practical knowledge is powerful then therotical knowledge.
