Sorry for bad handwriting, while there are other ways to do this, if you can just know how to simply find the legs from the two points it is very simple!
To solve this question, we have to find the acceleration of the car first. Acceleration refers to the rate of change of velocity of an object with respect to time.
Acceleration [A] = [V0 - V1] / T
Where VO = Initial velocity and V1 = Final velocity T represent time.
V0 = O
V1 = 18
T = 8
A = [ 0 - 18] / 8 = - 2.25
A = - 2.25 M/S^2.
To find force, we are going to use the formula: F = MA
F = ?
M = 1550
A = - 2.25
F = 1550 * - 2.25 = 3487.5
Therefore, F = -3487.5 N
Hey!
Hope this helps...

This really depends on what the question asks, because if you substitute 0 for x, the equation comes to 0 > 0 (which is a logical error), if you substitute 1 for x, the equation comes to 0 > -5 (which is the correct answer). If you substitute -28 for x, you get 0 > 28 (and we know 28 will always be greater than 0, but 0 will never be greater than any positive number), this is the same if you were to substitute -36 for x, you get 0 > 36
So the correct answer is D.) x > 1
because you get 0 > -5 (when you plug in 1 for x), and 0 will always be greater than any given negative number...

One more thing, this question is asking you to MAKE IT TRUE, IF it said 0 ≥ -3x - 2x... THAN A, B, and C would be correct, OR IF it said 0 ≤ -3x - 2x... THAN B and D would be correct, BUT because it only says 0 > -3x - 2x... THAN ONLY D is correct...
With a simple change of signs, you can dramatically change the answer to this equation
