The particle moves rectilinearly with acceleration a = 2B; where B = -0.5 m/s². At the instant t = 0, the particle coordinate Xo = 0; speed Vo = A; where A = 2 m/s. Find: a) the velocity of the particle at the end of the third second; b) the modulus of average speed for the first 3 seconds of movement; c) the path traversed by the particle during this time.

Thank you
