We will use two definitions to solve this problem. The first will be given by the conservation of energy, whereby the change in kinetic energy must be equivalent to work. At the same time, work can be defined as the product between the force by the distance traveled. By matching these two expressions and clearing for the Force we can find the desired variable.
Thus the force acting on the sled is,
Replacing,
Therefore the Force acting on the sled is 32N
Newton's first law;
"An object in motion stays in motion, an object at rest stays at rest , an object in space stays in space unless an unbalanced force acts on it "
Not so sure of the law
Answer:
F = 810 [N]
Explanation:
To solve this problem we must use the acceleration of gravity of the moon, which according to information provided by the internet we can see that the gravitational acceleration corresponds to 1.62 [m/s^2].
The weight of a body corresponds to the product of mass by gravity, so with the following equation we can find the weight.
F =m*g
F = 500 * 1.62
F = 810 [N]
