The resulting motion can be determined using the Pythagorean theorem, as the two components (north and east) are at right angles. To find the direction, trigonometry is applied, yielding Ф=arctan(3.8/12)=17.57° north of east.
Newton's First Law: A body remains in its current state of motion or at rest unless a force acts upon it.
Newton's Second Law: Motion changes are proportional to the applied force and oriented in the same direction.
Newton's Third Law: Every action has a corresponding and opposite reaction.
Tasks that would be challenging to perform in orbit include:
-operating a valve
-navigating on foot
-attempting to take a shower
-remaining still
<span>First, apply Newton's second law of motion: F = ma.
Force equals mass times acceleration.
This law describes force as the product of mass multiplied by acceleration (which is different from velocity). As acceleration is the variation in velocity over time,
we have force = (mass * velocity) / time,
leading us to conclude that (mass * velocity) / time will equal momentum / time.
Hence, we derive the equation mass * velocity = momentum.
Momentum = mass * velocity.
For the elephant, with a mass of 6300 kg and velocity of 0.11 m/s,
Momentum = 6300 * 0.11,
resulting in P = 693 kg (m/s).
For the dolphin, having a mass of 50 kg and moving at 10.4 m/s,
Momentum = 50 * 10.4,
yielding P = 520 kg (m/s).
Thus, the elephant has a greater momentum (P) due to its larger size.</span>
I do not concur with her stance. The concept of planetary motion emerges from a collaborative effort involving Johannes Kepler and Sir Isaac Newton. I believe Tycho Brahe's role was minimal since it was really Kepler who made the significant discoveries.
