Question
A particles position along the X axis is described by the function x(t)= A t + B t^2, where t is in seconds, x is in meters, and the constants A and B are given.
Randomized variables A=-4.2 m/s B=7.9 m/s^2
Enter an expression, in terms of A, B, and t, for the velocity of the particle as a function of time. At what time, in seconds, is the particles velocity zero?
