### Challenge Question ![[Challenge Problem 1 - Figure 1.png]] A block of mass $m$ is connected by two strings, $\text{String A}$ and $\text{String B}$, as shown in Figure 1. $\text{String A}$ connects the block to a vertical wall and $\text{String B}$ connects the block to the horizontal ceiling. $\text{String A}$ moves vertically upwards with a constant velocity $v$ and $\text{String B}$ moves horizontally to the right with a constant velocity $v$ such that the block moves vertically upwards. Both $\text{String A}$ and $\text{String B}$ are inextensible. Derive an expression for the relationship between the rate of change of the tension force in $\text{String A}$ and the rate of change of the tension force in $\text{String B}$ with respect to time.
