A construction crew must use a lever to lift a boulder. The mechanical advantage of the lever is 6 and the lever applies a force of 1600 N to the rock. What is the force that the construction crew must apply to the lever?

A.267 J
B.534 J
C.134 J
D.380 J

The formula to calculate the force applied by the construction crew is:

Force = Mechanical Advantage * Force Applied by the lever

Substituting the given values:

Force = 6 * 1600 N
Force = 9600 N

Therefore, the force that the construction crew must apply to the lever is 9600 N.

The correct answer is not provided.
