Final answer:
To calculate the magnitude of the total acceleration of the skip as it reaches a level of 2.7 ft below the top, you can use the equations for x-component and y-component of acceleration. Substitute the values of x and y at that level and find the corresponding components. Finally, calculate the magnitude of the total acceleration using the formula a^2 = ax^2 + ay^2.
Step-by-step explanation:
To calculate the magnitude of the total acceleration of the skip as it reaches a level of 2.7 ft below the top, we need to determine the components of acceleration in the x and y directions. The x-component of acceleration is given by ax = -x(2/35) * (d^2x/dt^2), where x is the position of the skip along the track. The y-component of acceleration is given by ay = 2y(2/35) * (dy/dt)^2. At the level 2.7 ft below the top, we can substitute the values of x and y into these equations to find the corresponding values of ax and ay. Finally, the magnitude of the total acceleration (a) is given by a^2 = ax^2 + ay^2.
