Question

1. a crate on a construction site has a two forces acting on it. the downward pull of gravity exerts a force of 65, 500 n, while a crane exerts an upward force of 70, 200 n. what is the net force on the crate?

135, 700 n downward
4700 n upward
135, 700 n upward
4700 n downward

Explanation:

Step1: Define upward as positive and downward as negative

Let \(F_{gravity}=- 65500\space N\) (downward) and \(F_{crane}=70200\space N\) (upward)

Step2: Calculate the net force \(F_{net}\)

Use the formula \(F_{net}=F_{gravity}+F_{crane}\)

Since the result is positive, the direction is upward.

Answer:

B. \(4700\space N\) upward
