Our digital product "Solution to the problem of the movement of points" contains a complete and detailed solution to the problem of the movement of two points along the x-axis according to the equations x1 = A1+B1t+C1t^2+D1t^3 and x2 = A2+B2t+C2t^2+D2t ^3. In this problem we need to find the velocities of points when their accelerations turn out to be the same.

To solve this problem, we can use the formula for the acceleration of a point on the x-axis, which is written as a = 2Ct + 6Dt^2. Equating the accelerations of points x1 and x2, we obtain the equation:

2C1t + 6D1t^2 = 2C2t + 6D2t^2

Having solved this equation for time t, we find the moment in time when the accelerations of the points are equal. By substituting the found value of time t into the equations for x1 and x2, we can find the velocities of the points at this moment in time.

Our digital product provides a detailed solution to this problem with a brief record of the conditions, formulas and laws used in the solution, the derivation of the calculation formula and the answer. We also ensure that the structure of the html code is preserved for ease of use and the text is beautifully designed for better perception of the material.

The product description is not related to problem 11081, which is a math problem. If you want a solution to this problem, I can help you solve it.

Problem 11081 is to find the velocities of two points moving along the x-axis according to the equations x1 = A1+B1t+C1t^2+D1t^3 and x2 = A2+B2t+C2t^2+D2t^3 when their accelerations are are equal.

To solve this problem, it is necessary to find the derivatives of the functions x1(t) and x2(t) in order to find their accelerations.

x1'(t) = B1+2C1t+3D1t^2 - speed of the first point x2'(t) = B2+2C2t+3D2t^2 - speed of the second point

x1''(t) = 2C1+6D1t - acceleration of the first point x2''(t) = 2C2+6D2t - acceleration of the second point

In order for the accelerations to be equal, it is necessary to solve the equation:

x1''(t) = x2''(t)

2C1+6D1t = 2C2+6D2t

6D1t - 6D2t = 2C2-2C1

t = (C2-C1)/(3D1-3D2)

Substituting the found value of t into the expressions for speeds, we get:

x1'(t) = B1+2C1t+3D1t^2 = B1+2C1(C2-C1)/(3D1-3D2)+3D1(C2-C1)^2/(9D1^2-18D1D2+9D2^2)

x2'(t) = B2+2C2t+3D2t^2 = B2+2C2(C2-C1)/(3D1-3D2)+3D2(C2-C1)^2/(9D1^2-18D1D2+9D2^2)

Thus, the velocities of the points at the moment of time when their accelerations are equal will be equal to x1'(t) and x2'(t), which were found above.
