You can't.
Work = (force) x (distance) .
You can squeeze distance out of the speed, but there's no way to determine the FORCE being used.
If there's no friction and the car is traveling in a straight line, then NO force is needed to keep it going. It just keeps going. (Newton's 1st law of motion.)
The answer is 4 kg m/s
because p = m x v , 2 kg x 2m/s = 4 kg m/s
Answer:
Explanation:
Let
h = height of balloon (in feet).
θ = angle made with line of sight and ground (in radians).
h = 300 tanθ
now can be written as
When θ = π/4,
Speed is just how fast the object is moving, while velocity is the speed and <em>direction </em>of the object.
edit* Direction would be something such as North, East, etc.
It's short for magnetic levitation technology; it uses the opposite attraction of magnets to keep something in the air; e.g. a train with magnets on the bottom facing south and the tracks that also have south facing magnets.
