A particle’s position along the x-axis is described by x(t) = A t + B t2, where t is in seconds, x is in meters, and the constants A and B are given below. Randomized Variables A = -4.4 m/s B = 6.3 m/s2 What is the velocity, in meters per second, of the particle at the time t1 = 3.0 s? What is the velocity, in meters per second, of the particle when it is at the origin (x = 0) at time t0 > 0?
