The answer is a. endothermic.
In endothermic reaction, as the name suggests, the reactants require energy absorption to form and complete the chemical reaction to form products.
And even if you don't know the answer, you can exclude all other answers by scientific logic and you will be left with the correct answer.
Hope this helps.
Cuz Of Newton’s third law, every actions there is an equal and opposite reaction.

Answer:
F = 2.113 x 10⁵ N
Explanation:
First we need to calculate the deceleration of the driver by using 3rd equation of motion:
2as = Vf² - Vi²
where,
a = deceleration = ?
s = distance = 5 cm = 0.05 m
Vf = Final Velocity = 0 m/s
Vi = Initial Velocity = 18 m/s
Therefore,
2a(0.05 m) = (0 m/s)² - (18 m/s)²
a = (- 324 m²/s²)/0.1 m
a = - 3240 m/s²
where, negative sign represents deceleration
From Newton's Second Law of Motion:
F = ma
F = (65 kg)(-3240 m/s²)
F = - 2.106 x 10⁵ N
So, he closest answer is:
<u>F = 2.113 x 10⁵ N</u>
A distance-versus-time graph for the moving object would curve upward for acceleration and curve downward for deceleration
