This was the essential question on a homework assignment. Speed tells how fast an object is moving but it does not tell the direction. Velocity tells how fast an object is moving and it also tells the direction. When velocity is positive, the object is moving up. When velocity is negative, the object is moving down.
The velocity of the object is 10 m/s.
3.00 m/s
Distance = Velocity*Time = 25.5*85 metres = 2167.5 metres.
The speed of the object would be 3 meters per second (45 meters ÷ 15 seconds).
To find the distance traveled in the first 5 seconds, we multiply the average velocity by the time traveled. If the object's velocity is constant, this distance is equal to the velocity multiplied by the time.
8ms-1
20 meters per second
The object is moving at the speed of 50 ms-1 .
The object will move a total distance of 80 meters, which is calculated by multiplying the speed (10 m/s) by the time (8 seconds).
The speed of the object is 5 m/s. Speed is calculated as distance divided by time, so 20 meters/4 seconds = 5 m/s.
Velocity measures both speed and direction that an object travels. The magnitude of velocity represents the speed of the object, while the direction of velocity indicates the direction in which the object is moving.
The final velocity of an object in free-fall after 2.6 seconds is approximately 25.48 m/s. The distance the object will fall during this time is approximately 33 meters.
