two workers push horizontally in the same direction on a 250 kg wooden crate that is on a wooden floor .
To determine the resulting force produced by the two workers pushing the wooden crate, we need to consider the individual forces applied by each worker and determine their net force.
First, let's assume that worker A applies a force of 200 N to the crate, while worker B applies a force of 150 N. Since the workers are pushing in the same direction, the forces they apply can be added together.
To calculate the net force, simply add the individual forces:
Net force (F_net) = F_A + F_B
= 200 N + 150 N
= 350 N
Hence, the resultant force on the wooden crate is 350 Newtons. This resulting force determines the acceleration (or deceleration) of the crate according to Newton's second law of motion: F = ma, where F is the net force, m is the mass of the crate, and a is the acceleration.
In this scenario, to find the crate's acceleration, we need to rearrange the equation in terms of acceleration:
a = F_net / m
= 350 N / 250 kg
= 1.4 m/s^2
Therefore, the crate is experiencing an acceleration of 1.4 meters per second squared in the direction of the workers' push.
