Answer:
1) The net force is 5 N. The box is accelerating 10 m/s
2) The net force is 6.986 N. It is accelerating. Normal Force is 16.986
Explanation:
1) 20 N forward - 15 N backwards = a net force of 5 N
Acceleration: Acceleration = Net Force * Mass ( derived from Force = mass * acceleration).
a = 5 N / 2 kg
a= 2.5 m/s^2
2)
a) 1000 grams = 1 kg ... no
d) 1000 centigrams
Energy flows with kinetic energy
Is the same as the amount that is used to make the chemical reaction. The Law of conservation of Matter states that matter cannot be added or removed, or created or destroyed. This means that the amount of matter is always the same
