Question

Emily and Patrick are trying to lift their friend hunter onto a tree branch. Emilio is pushing hunter upward with a force of 250 N. Patrick is pushing hunter upward with a force of 310N. Earth’s gravity is pulling Hunter downward with a force of 520 N

Assume all other forces on hunter are balanced. Which statement describes the forces on hunter ?

Answer 1

Answer:

The forces are unbalanced, so there is net force on the hunter.

Explanation:

To know which option is correct, we shall determine the net force acting on the hunter.

From the question given above, the following data were obtained:

Force applied by Emilio (F₁) = 250 N

Force applied by Patrick (F₂) = 310 N

Force of gravity (F₉) = 520 N

Next, we shall determine the total force applied in lifting the hunter. This can be obtained as follow:

Force applied by Emilio (F₁) = 250 N

Force applied by Patrick (F₂) = 310 N

Total force applied (Fₜ) =?

Fₜ = F₁ + F₂

Fₜ = 250 + 310

Fₜ = 560 N

Finally, we shall determine the net force acting on the hunter. This can be obtained as follow:

Force of gravity (F₉) = 520 N

Total force applied (Fₜ) = 560 N

Net force (Fₙ) =?

Fₙ = Fₜ – F₉

Fₙ = 560 – 520

Fₙ = 40 N

Thus the net force acting on the hunter is 40 N

From the calculations made above, we can see that the net force acting on the hunter is 40 N.

Therefore, the correct answer to the question is:

The forces are unbalanced, so there is net force on the hunter.
