Power = (energy) / (time) =(200 newtons x 4 meters) / (4 seconds) =200 newton-meters per second = 200 watts
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.
3.00 m/s
Distance = Velocity*Time = 25.5*85 metres = 2167.5 metres.
8ms-1
3 m/s
20 meters per second
The object is moving at the speed of 50 ms-1 .
The average speed is 5 metres per second.
Velocity tells you what speed a moving object travels at and in what direction.
The speed of the the object is 20/5 = 4 metres per second.In order to answer the question in terms of velocity, it is necessary to know the direction of motion because velocity is a vector.
IF the object begins from rest, then it travels 1.5 x 10^8 meters. (rounded)
This is known as displacement, and is generally measured in meters :)
The velocity = (location at 40 seconds - location at 20 seconds)/20 in the direction in which the object is moving.
