[ because reactants higher in energy ]
____________________________________
By the given graph, conclusion can be made that reactants have higher energy than products, hence for the reaction to take place, reactants must loose energy to form products. And once the energy is released, that reaction is called Exothermic.

Answer:
12824.74 N
Explanation:
mass of bullet, m = 21 g = 0.021 kg
distance, s = 114 cm = 1.14 m
final velocity, v = 1180 m/s
initial velocity, u = 0
Let F be the force .
By use of work energy theorem
Work done = change in kinetic energy
F x s = 1/2 m v² - 1/2 mu²
F x 1.14 = 0.5 x 0.021 x 1180 x 1180
F = 12824.74 N
