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):

The distance traveled and the time it takes to travel are both going up at a steady rate. The distance goes from lap 1, lap 2, lap 3, lap 4. The time is increasing by a minute each time. When both the x and y scenario are increasing at a STEADY RATE the line will be linear. B displays a linear line.
2.5N
Explanation:
Given parameters:
Mass of object = 500g
Acceleration = 5m/s²
unknown:
Resultant force = ?
Solution:
According to Newton's second law "the net force on a body or the resultant force is the product of its mass and acceleration".
Resultant or net force = m x a
where m is the mass
a is the acceleration
Now we need to convert the mass to kg
1000g = 1kg
500g =
= 0.5kg
Therefore;
Input the parameters:
Force = 0.5 x 5 = 2.5N
