### Physics Problem on Forces and AccelerationA 40-kg crate is being lowered with a downward acceleration of \( 2.0 \, \text{m/s}^2 \) by means of a rope.#### Questions:**(a)** What is the magnitude of the force exerted by the rope on the crate? \( \_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_ \text{N} \)**(b)** What would be the magnitude of the force exerted by the rope if the crate were being raised with an acceleration of \( 2.0 \, \text{m/s}^2 \)? \( \_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_ \text{N} \)---For educational purposes, explain that these problems are related to Newton's second law of motion, which states that \( F = ma \), where \( F \) is the net force, \( m \) is the mass, and \( a \) is the acceleration. To solve these problems, consider the gravitational force acting on the crate and the net force due to the acceleration. Discuss how to determine the tension in the rope by setting up the equations for both lowering and raising the crate scenarios.

a)Draw the free-body diagram of the crate.

Consider an object at rest on a rough horizontal surface. Which of the following is necessarily correct if we use the model of friction described in the videos and book? The force of friction on the object is smaller than or equal to μg FN, where μs is the coefficient of static friction and FN is the normal force exerted on the object by the surface. The force of friction on the object is proportional to the normal force exerted by the surface on the object. The force of friction on any object opposes motion; since the object is at rest, the force of friction is zero. The force of friction on the object is proportional to the object's weight, i.e. Ff = p.mg, where μs is the coefficient of static friction, m is the mass of the object, and g is acceleration due to Earth's gravity.
