A particle's position along the x-axis is described by: x(t)=At + Bt

A particle's position along the x-axis is described by: x(t)=At + Bt where t is in seconds, x is in meters, and the constants A and B are given below. Randomized Variables A = -4.3 m/s B = 4.9 m/s (a) What is the velocity, in meters per second, of the particle at t = 3.0 s? (b) What is the velocity, in meters per second, of the particle when it is at the origin (x=0) at t > 0?
