A particle moves along the x-axis with position function x(t) = Atz + Bt3, where A = 3 m 5'2 and B = % m 53 are constants. Find the instantaneous velocity vx and the instantaneous acceleration ax of the particle at time t: 2 5. Give your answers by entering the appropriate integer numbers in the two empty boxes below (you don't need to concern yourself with significant figures in this question). At time t=25 : vx=|:|ms_1. At time t=23 : ax=|:|ms_2. You may use the following standard derivative: dCr" dt = nCt" _ 1 where C and n are any constants
