Answer:
Mass = 8kg
Force = 78.4
Acceleration = ?
Now,
According to formula,
Force = Mass*Acceleration
78.4N = 8kg*Acceleration
78.4/8 = Acceleration
Acceleration(a) = 9.8 m/s^2

Answer:
Explanation:
Kinetic energy involves motion so something that is not moving has zero kinetic energy.
Potential energy does not involve motion and is based on position in a field like gravity and magnetic.
Answer: Distance
I’m not sure if it is correct, but I am pretty sure it is......
I hope this helps :)
You need to know the specific heat capacity of air.
Then energy needed = 0.005 x sp.heat.cap x 10
