Answer:
Falso. Se requiere de dos vectores de igual magnitud pero antiparalelos entre sí.
Explanation:
Un vector es un elemento caracterizado por tener magnitud y dirección, sea
un vector tal que la resultante sea
(vector nulo). Por Álgebra de los Reales se sabe que todo vector tiene su inverso, es decir, que existe un vector
tal que:

![(v_{x}, v_{y}) + [-(v_{x},v_{y})] = (0,0)](https://tex.z-dn.net/?f=%28v_%7Bx%7D%2C%20v_%7By%7D%29%20%2B%20%5B-%28v_%7Bx%7D%2Cv_%7By%7D%29%5D%20%3D%20%280%2C0%29)

Esto significa, que el siguiente sistema de ecuaciones debe satisfacerse:


Se requiere de dos vectores de igual magnitud pero antiparalelos entre sí. En consecuencia, la anterior afirmación es falsa.
Answer:
minimum stopping distance will be d = 75 m
Explanation:
Maximum force exerted by the bracket is given as
F = 9000 N
now we know that mass of the object is
m = 6000 kg
so the maximum acceleration that truck can have is given as



now for finding minimum stopping distance of the truck



Answer:
Explanation:
1) No take-off possible
2) The downward force is greater than the upward force.
3) 2000 + 950 = 2950 N upward
Answer:
a. If c = 20 cm, then the mass of the brain is m = 5 g.
b. At c = 20 cm, the brain's mass is increasing at a rate of 15.75 g/cm.
Explanation:
From the equation

we have
a. for c = 20 cm

then the mass is m(20) = 5 g.
b. In order to find the rate of change, first we derivate

Evaluated at c = 20 cm, we have

So, at c = 20 cm, the mass of the brain is increasing at a rate of 15.75 g/cm.
Answer:
<h3>The answer is option B</h3>
Explanation:
To find the force acting on an object we use the formula
<h3>force = mass × acceleration</h3>
From the question
mass = 3.5 kg
acceleration = 0.80 m/s²
We have
Force = 3.5 × 0.8
We have the final answer as
<h3>2.8 N</h3>
Hope this helps you
