Calculating Velocity and Position Vectors of a Faulty Model Rocket

1. How can we calculate the velocity vector as a function of time for a faulty model rocket moving in the x-y plane with given acceleration components? 2. How can we determine the position vector as a function of time for the same rocket based on the velocity vector obtained earlier?

Calculating Velocity Vector as a Function of Time:

To find the velocity vector as a function of time, we need to integrate the acceleration with respect to time. The given components of acceleration are ax(t) = at and ay(t) = 8 - t. Integrating ax(t) = at with respect to time, we get the x-component of velocity: vx(t) = (1/2)at^2 + Cx, where Cx is the constant of integration. Integrating ay(t) = 8 - t with respect to time, we get the y-component of velocity: vy(t) = 8t - (1/2)t^2 + Cy, where Cy is the constant of integration. At t = 0, the rocket is at the origin and has velocity Vo = Vom* + 00. Since the positive y-direction is vertically upwards, this means vy(0) = Vom. Substituting t = 0 into vy(t), we get Cy = Vom. Therefore, the velocity vector as a function of time is given by: V(t) = (vx(t), vy(t)) = ((1/2)at^2 + Cx, 8t - (1/2)t^2 + Vom).

Calculating Position Vector as a Function of Time:

To find the position vector as a function of time, we need to integrate the velocity vector with respect to time. Using the velocity vector obtained in the previous step, we can integrate each component separately. Integrating vx(t) = (1/2)at^2 + Cx with respect to time, we get the x-component of position: x(t) = (1/6)at^3 + Cxt + Dx, where Dx is the constant of integration. Integrating vy(t) = 8t - (1/2)t^2 + Vom with respect to time, we get the y-component of position: y(t) = 4t^2 - (1/6)t^3 + Vomt + Dy, where Dy is the constant of integration. The correct answer is, the position vector as a function of time is given by: r(t) = (x(t), y(t)) = ((1/6)at^3 + Cxt + Dx, 4t^2 - (1/6)t^3 + Vomt + Dy). Note: The constants Cx, Dx, and Dy can be determined using initial conditions or additional information provided in the problem.
