• AQ I: In Lab 04, we used a force table to study the interaction of three forces. In that lab we did not have a way to deal with the uncertainties associated with angles inside trig functions (for finding components of vectors). But now we do! Suppose we want to find the x-component of the force F₁: F_1x = m g sin θ where we have measured m ± δm and θ ± δθ. Find an expression for the relative uncertainty in F_1x (i.e., find F_1x/δF_1x ).
• AQ II: In class, we talked about a method for finding the maximum value of a function. Take a look at the kinematic equation y_f = y_i + v_iy t - (1/2) g t² (here I've set the initial time equal to zero and just written Δt as simply t). Use the method to find an expression for the time, t, at which the maximum value of y_foccurs. Find the corresponding maximum value of y_f . Use this value of t to compute the final vertical velocity. Does your result make sense?
