Answer:To find the acceleration of the crate, you can use Newton's second law of motion, which states that the acceleration of an object is equal to the net force acting on it divided by its mass. In this case, the mass of the crate is 130.0 kg and the net force acting on it is the applied force of 690.0 N minus the friction force.
You can use the following formula to calculate the acceleration:
Acceleration = (Net force) / (Mass)
To find the friction force, you can use the formula for friction force:
Friction force = coefficient of friction * normal force
The normal force is the force that the floor exerts on the crate perpendicular to the surface, and it is equal to the mass of the crate multiplied by the acceleration. So, you can substitute the mass of the crate and the acceleration into the formula for the normal force to find the friction force:
Friction force = coefficient of friction * (Mass * Acceleration)
To find the acceleration, you can substitute these values into the formula for acceleration and solve for the acceleration:
Acceleration = (Net force) / (Mass)
= (690.0 N - Friction force) / (130.0 kg)
You can solve for the acceleration by substituting the value for the friction force and solving for the acceleration.
