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.
Power = (energy) / (time) =(200 newtons x 4 meters) / (4 seconds) =200 newton-meters per second = 200 watts
3.00 m/s
Distance = Velocity*Time = 25.5*85 metres = 2167.5 metres.
8ms-1
3 m/s
The acceleration of gravity is 9.8 meters/sec2 .After 6 seconds, the object's speed is (6 x 9.8) = 58.8 meters/sec .It's velocity is 58.8 meters per second downward.
20 meters per second
The object is moving at the speed of 50 ms-1 .
Pressure is defined as the amount of force exerted on an object (in Newtons) divided by the area over which the force is exerted (in meters). Velocity is defined as the displacement of an object (in meters) divided by the time interval over which the object was displaced (in seconds).
Velocity tells you what speed a moving object travels at and in what direction.
The average speed is 5 metres per second.
velocity
The velocity = (location at 40 seconds - location at 20 seconds)/20 in the direction in which the object is moving.
