A box with a mass of [m] kg is acted upon by two forces, F1 = [F1] N and F2 = [F2] N. Assuming the block moves on a frictionless surface, determine the magnitude of the box’s acceleration. Express your answer in m/s2. The view in the figure is from above.

We want to add a state category variable to the regression analysis. The state category variable has four possible answers (MO =1, FL =2, WA =3, NY = 4). In this case, we need to convert the state category variable into _________________ dummy variables for regression analysis.

A force of [F] N pushes a [m] kg box along the +x axis on a horizontal frictionless surface. The figure shows the velocity and displacement of the box. At time t = 0, the box is at displacement x1 = [x1] m and moves with an initial velocity of v0 = +[v0] m/s. Given x2 = [x2] m, determine the magnitude of the velocity v1 in m/s. Note that the positive directions of force, displacement, and velocity are all toward the right.

The spring constant of a massless spring can be determined from the force-displacement graph, which shows the force applied to the spring and the corresponding displacement. x1 = [x] m and F2 = [F] N. A person pulls the spring slowly until it is stretched by [dx] m. Determine the work done by the person to stretch the spring. Express your answer in joules.
