The question involves the knowledge of kinematics and dynamics. The answers are;
a) Time taken to stop the car = 10 s
b) The operation that slows the car is Friction
c) The size of the force = 1200 N
<h3>
What is Deceleration ?</h3>
Deceleration is the opposite of acceleration. When an object is going to rest, it will be decelerating and the final velocity will be equal to zero.
Given that the driver of a car moving at 15 m/s along a straight level road applies the brakes. The car decelerates at a steady rate of 3/2 m/s²
a) How long does the car take to stop can be found by using the formula
v = u - at
Where
Substitute all the parameters into the formula
0 = 15 - 1.5t
1.5t = 15
t = 15/1.5
t = 10 s
b) The description of the operation that slows the car down after the brake pedal is pressed is simply friction.
c) If the mass of the car is 800. The size of the force slowing the car down will be F = ma
F = 800 × 1.5
F = 1200 N
Therefore, the time taken to stop the car is 10 s and the force slowing the car down is 1200 N

La respuesta correcta para esta pregunta abierta es la siguiente.
Para el psicoanálisis, las relaciones tempranas son las relaciones a posteriori entre los padres del recién nacido y el bebé mismo. Estas relaciones son fundamentales en los procesos de constitución subjetiva para el discurso parental para entender los aspectos del desarrollo infantil y sus diferentes estados o teorías de desarrollo para ir comprendiendo cada aspecto de la interrelación y el comportamiento entre las partes.
Para el psicoanálisis, el recién nacido está llegando a un núcleo familiar que ya está establecido y se basa en conocimientos, tradiciones y experiencias de los padres que han recibido de generaciones anteriores, y éstas van a influir directamente en la interrelación permanente con los primeros años del crecimiento del bebé.
