Answer:
The rocket will appear larger than it actually is
Answer:
The short answer is that velocity is the speed with a direction, while speed does not have a direction.
Explanation:
Speed is how fast an object is moving. It is calculated by the displacement of space per a unit of time. Velocity is the rate at which an object changes position in a certain direction. It is calculated by the displacement of space per a unit of time in a certain direction. Velocity deals with direction, while speed does not.
F is force, m is mass and a<span> is acceleration. The math behind this is quite simple. If you double the force, you double the acceleration, but if you double the mass, you cut the acceleration in half.</span>
I think your second figure should be 6km/hour if that is the case then this is the answer.
Answer
A. Negative. this is because your speed is reducing which means you are decelerating or rather going at a negative (acceleration).
