Se calcula que la aceleración es - 8,35 m/s.
<h3 /><h3>¿Qué es la aceleración?</h3>
Ahora sabemos lo siguiente de la pregunta;
Velocidad inicial (u) = 60 km/h o 16,7 m/s
Tiempo empleado (t) = 2 s
Dado que;
v = tu + en
v = 0 m/s porque el carro se detenía
tu = -en
a = -(u/t)
a= -1(6,7 m/s/2 s)
a =- 8,35 m/s
La aceleración es negativa porque la velocidad disminuye con el tiempo.

Answer:
The correct option is C. 5
Therefore,

Step-by-step explanation:
Simplify

Solution:
Using Identity

So in the given expression

Therefore,

Therefore,

There is little context to go off of but the answer should be variable
So if 6 out of 40 are incorrect, 40-6= 36 must be correct.
In order to gain percentage you do proportions.
36/40 = x/100.
Multiply 36 times 100 then divide by 40, which is 90.
The answer is 90%.
90% of the questions he got were correct.
