Determine the speed of the cart (v) as a function of the angular position of the cart on the loop (let straight down be \(\theta\) =0°), the spring constant (k), the initial compression of the spring (s), H, m, and g.

We will now allow objects to move through three dimensional space. We will still, however, restrict our model with the following approximations. The object is acted on by constant forces. The object’s size and shape are unimportant. The object is classical.

In a nutshell, what we’ve done is used the acceleration of the truck to find the angular acceleration of the pulley, and then used the angular acceleration of the pulley to find the acceleration of the block.

(The current along the inner wire flows toward the top of the page, resulting in magnetic field pointing directly out of the page in the area of interest.) This equation says that the time derivative of the derivative of the current is equal to the product of the derivative of the current and a numerical factor.
