The time taken for the car to overtake the truck is 7.559 seconds. See the explanation below. See the explanation for this acceleration problem below.
<h3>What is acceleration?</h3>
Any process in which the velocity varies is referred to as acceleration. Because velocity is both a speed and a direction, there are only two ways to accelerate: modify your speed or your direction—or both.
<h3>What is the calculation justifying the above answer?</h3>
Given:
Acceleration of the car Ac= 3.4m/s²
Acceleration of the Truck At = 2.1m/s²
We know that the car overtakes the truck after 60m.
Hence, the time required by the car to overtake the truck is the same time required by the truck to travel 60m
Therefore,
s=ut+ 1/2 AtT²; u=0
t = √(2s/At)
= √(2 * 60) /2.1
= √120/2.1
= √57.1428571429
= 7.559289446018

Full Question:
A car and a truck start from rest at the same instant, with the car initially at some distance behind the truck. The truck has a constant acceleration of 2.10 m/s2 and the car an acceleration of 3.40 m/s2. The automobile overtakes the truck after the truck has moved 60.0 m.
How much time does it take the car to overtake the truck? Express your answer with the appropriate units.
Answer:
B. Offers few testable hypothesis that allow one to determine its validity.
Explanation:
Freud´s theory of personality was based on the hypothesis of unconsious mental processes, which influenced people's life. He built a theory from his clinal practice, this means he listened to his pacients and built a theory from that experience.
He is criticized because of his method, he did not turned to cientific proof to validate his theory. This means his hypothesis were not to be proof by empiric or statistics procedures. Although he did wrote about his experience with his pacients.

Explanation:
The Greek underworld unlike the Christian Hell is a kingdom. In Greek mythology is told that the underworld was ruled by Hades and his wife and they both ruled the kingdom of dead (unlike the Christian hell that is ruled by Satan). As a kingdom, the Greek hell had various “popular spaces” as the five rivers that travel through the underworld that helps divide it into four regions; it also has fields and meadows for the souls that live there. In Christian hell it’s thought that only bad people that had done bad actions while living go through hell, thou in Greek hell, they thought that everyone, no matter your actions, end up in the underworld. The closest description of Christian hell would be Dante’s Inferno which describes the adventures of Dante walking in the eight circles of hell (due to the 8 deadly sins). While to enter the Greek hell, you need to pay two coins and from that point it is a transition, from the gates to some part of the underworld.
