In a thunderstorm, the formula: M = t 5.6 gives the approximate distance, M , in miles, from a lightning strike if it takes t se
1 answer:
Answer:
Explanation:
In a thunderstorm the lightening is seen first then the roar of the lightening is heard because of the fact that speed of the light is much greater than the speed of the sound.
Given that:
Relation
M= 7 miles
t=?
where:
t= time in seconds
M= distance in miles
Now,
Putting the given values in the relation above

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):
