Answer:
The acceleration of the plane is -2.14 m/s² ⇒ 2nd answer
Explanation:
<u><em>Acceleration</em></u> is the rate of change of velocity
The unit for acceleration is meters per second square
The rule of the acceleration is: →
where a is the acceleration, u is the initial velocity, v is the final velocity
and t is the time
An airplane traveling 245 m/s east experiences turbulence so the pilot
slows down to 230 m/s
It takes the pilot 7 seconds to slow down to this speed
We need to find the acceleration of the plane
Lets use the rule above
→ u = 245 m/s , v = 230 m/s , t = 7 seconds
→
→
→ The acceleration is -2.14 m/s²
<em>The acceleration of the plane is -2.14 m/s²</em>

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):
