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.
To find the speed of an object, you can use the formula: speed = distance/time. In this case, the object travels 100 meters in 50 seconds. Therefore, the speed is 100 meters ÷ 50 seconds = 2 meters per second.
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.
The speed of the object would be 3 meters per second (45 meters ÷ 15 seconds).
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.
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.
