drawing shows a 25.0-kg crate that is initially at rest. Note that the view is one looking down on the top of the crate. Two forces, and , are applied to the crate, and it begins to move. The coefficient of kinetic friction between the crate and the floor is mk = 0.350. Determine the magnitude and direction (relative to the x axis) of the acceleration of the crate.

WHAT IS THE ANSWER?

this was posted in 2009 and still doesn't have an answer. it's 2018 now. rip.

it is now 2020, and it still does not have an answer lol

The coefficient of kinetic friction between the crate and the floor is mk = 0.350. Determine the magnitude and direction (relative to the x axis) of the acceleration of the crate.

Without knowing the magnitudes and direction of the forces, we cannot calculate the acceleration of the crate. Please provide more information or a diagram with the values for the forces.

To determine the magnitude and direction of the acceleration of the crate, we need to consider the forces acting on it and apply Newton's second law of motion, which states that the net force acting on an object is equal to the product of its mass and acceleration (F = ma).

In this case, there are two forces acting on the crate: the applied force (F_applied) and the force of friction (F_friction). The direction of the applied force will determine the direction of acceleration, while the magnitude of the net force will determine the magnitude of acceleration. Let's break it down step by step:

1. Find the force of friction:
The force of friction can be calculated by multiplying the coefficient of kinetic friction (μk) by the normal force (N) exerted on the crate by the floor. The normal force is equal to the weight of the crate (mg). Therefore:

F_friction = μk * N
= μk * mg

2. Find the applied force:
The applied force (F_applied) is given in the problem.

3. Determine the net force:
The net force (F_net) is the difference between the applied force and the force of friction:

F_net = F_applied - F_friction

4. Calculate the acceleration:
Using Newton's second law, the net force can be related to the mass (m) and acceleration (a):

F_net = ma

Solve for acceleration:

a = F_net / m

5. Determine the direction:
The direction of acceleration will be the same as the direction of the net force, which is determined by the applied force.

Now, you have the steps to find the magnitude and direction of the acceleration of the crate. Plug in the given values and solve the equations to find the answer.
