Answer:
The kinetic energy of the wagon is 967.0 J
Explanation:
Given that,
Force = 120 N
Mass = 55 kg
Height = 8 m
We need to calculate the kinetic energy of the wagon
Using newtons law



Using equation of motion

Where,
v = final velocity
u = initial velocity
s = height
Put the value in the equation


Now, The kinetic energy is



Hence, The kinetic energy of the wagon is 967.0 J
Catalysts
a catalyst is something added to a reaction that speeds it up (or lowers the activation energy)
increasing the temp would speed up the whole reaction but not lower the activation energy
so B.
Answer:
analize the levels of kinetic and potential energy and look up a guide to graph it and follow that
