What is the magnitude of force required to accelerate a car
2 answers:
Answer:
8,075N
Step-by-step explanation:
The information we have is:
Mass:
Acceleration:
We are asked to find the force that is necessary to create that acceleration in the given mass.
For this we use the equation of Newton's second law:
and now we susbtitute all the values into the equation to find the force :
The magnitude of the force required is 8,075N

Answer:
D. x = 0.5
Step-by-step explanation:
A graphing calculator is the quickest way to get to an answer here.
f(x) = g(x) for x = 0.5
__
We can find the y-intercepts of the two functions to be ...
f(0) = -3
g(0) = -2
We know the x-intercept of g(x) is x=4. The x-intercept of f(x) will be a value less than 1, because f(1) = 1. (The function crosses the x-axis between x=0 where f(x) < 0 and x=1, where f(x) > 0.)
Considering these intercept points, we know the value of x for f(x)=g(x) will be between x=0 and x=1. There is only one answer choice in that interval:
x = 0.5
