Slope and Deflection

The slope in a deflected beam is described as an angle in radians made by the tangent of the section with the original axis of the beam. The deflection at any point on the axis of the beam is defined as the lateral displacement of the point before and after loading.

Question

A motor winds the rope in B with a constant acceleration ab. Because of the pulley
system, the mass m in A slides in this way to the left over a horizontal axis.
Between m and the left end point of the horizontal axis, there is a spring (constant
k, unstretched length ). The coefficient of kinetic friction between m and the axis
is μK. When SA equals 1.5 m, Vв equals 6 m/s. For this situation, determine at that
instant the velocity of A and the acceleration of A.
Data: aв = 2 m/s², m = 2 kg, k

Combination of these equations leads to the solution: VA is 15 m/s to the left, and a = 101 m/s² to the
left.
