Aristotle, a pupil of Plato, diverged from his mentor’s philosophy in several key aspects. While Plato believed the soul was eternal, singular, and unchanging, Aristotle argued for its mortality.

1 .- A body moves from rest with constant acceleration of 8 m / s 2. Calculate: a) the speed is within 5 s, b) the distance traveled from rest, in the first 5 s.
Data:
v i = 0 (m / s)
a = 8 (m / s 2)
v f = v i + at = 0 (m / s) + 8 (m / s 2) x 5 (s) = 40 (m / s)
d = v i t + at 2 / 2 = 0 (m / s) x 5 (s) + 8 (m / s 2) x (5 (s)) 2 / 2 = 100 (m)
2 .- The velocity of a vehicle increases smoothly from 15 km / h to 60
