Final answer:
Due to the lack of a complete equation of motion, it is not possible to solve for y(-10) without the full initial value problem and associated parameters.
Step-by-step explanation:
To find the solution of the initial value problem with the given initial condition y(-10), we need an equation that describes y as a function of t. Based on the information provided, the motion equations are not clearly stated for y as a function of t, which makes it impossible to evaluate y at t = -10. Normally, if we have a complete equation such as y = yo + vot + ½at², we could plug in the values for vo (initial velocity), a (acceleration), and the given t value to solve for y. However, since the full motion equation and initial conditions are not provided, we cannot solve this problem directly. If the correct equation was provided (e.g., something similar to Uy(t) = -1.1 m/s + (-0.54 m/s²)t), then it would be a matter of substituting t = -10 into the equation to find the position at that time.
