im a bit confused on what the question is:(
if its just asking for the total number of km traveled it would be 21 km
<span>Subtract the forces in the horizontal direction from the forces in the vertical direction.</span>
Wave speed = fλ
=(5 x 10^14)(4 x 10^-7)
=2 x 10^8
Where f is the frequency and λ is the wavelength
Answer:
Surely Achilles will catch the Tortoise, in 400 seconds
Explanation:
The problem itself reduces the interval of time many times, almost reaching zero. However, if we assume the interval constant, then it is clear that in two hours Achilles already has surpassed the Tortoise (20 miles while the Tortoise only 3).
To calculate the time, we use kinematic expression for constant speed:

The moment that Achilles catch the tortoise is found by setting the same final position for both (and same time as well, since both start at the same time):

Current would flow between them and they would receive a terrible shock.
