Suppose you have a 193 kg wooden crate resting on a wood floor.

(a) What force do you need to exert horizontally on the crate so the crate starts moving?

Assume the coefficient of static friction for wood on wood is 0.4.

Answer :

Final answer:

The force required to start the wooden crate moving is 756.88 N.

Explanation:

To determine the force required to start the wooden crate moving, we need to calculate the maximum static friction force.

The maximum static friction force can be found by multiplying the coefficient of static friction (0.4) by the normal force acting on the crate. The normal force is equal to the weight of the crate, which can be calculated by multiplying the mass (193 kg) by the acceleration due to gravity (9.8 m/s²).

Therefore, the force required to start the crate moving is:

Force = 0.4 * (193 kg * 9.8 m/s²)

Force = 756.88 N
