To determine the velocity of an object moving at a constant speed, we need to divide the distance traveled by the time taken. In this case, the object travels a distance of 10 meters and takes 1.5 seconds to reach the ground.
Velocity = Distance / Time
Velocity = 10 meters / 1.5 seconds
Velocity = 6.67 meters per second
Therefore, the velocity of the object is 6.67 meters per second.
