Answer:
a = F/m
Explanation:
So we have to isolate a, in order to do this we need to move m to the other side, and we do that by diving both sides by m, resulting in a = F/m
a) PE=mgh=0.2*9.8*1.2=2.352 J
b) KE=PE=2.352 J
c) 
m/s
Answer:
B. Any object that has motion has potential energy, wow any object not in motion light with the potential to do work and kinetic.
Explanation:
Potential Energy is the energy possessed by a body by virtue of its position relative to others, stresses within itself, electric charge, and other factors. Kinetic Energy is energy which a body possesses by virtue of being in motion.
Hi,
The answer is D, Gravitational.
Hope this helps.

Translating the first sentence into equation we get, t = k(1/h)
where t is time in seconds, k is the constant and h is the horsepower. Substituting
the values in the equation we have, 12s = k(1/200) we have a k = 2400 seconds –
hp. To get the time at 240 hp we use the equation above and the constant, we
get, t = (2400 seconds-hp)(1/240hp) t = 10seconds.
