The problem that follow involve straight-line motion. The time t is in seconds unless otherwise stated.

Problem

At t = 0. a steel ball in a tank of oil is given a horizontal velocity v= 2i (m/s). The components of the ball’s acceleration, in m/s2 are ax = –1.2vx,ay = –8 – 1.2vy and az = –1.2vz. What is the velocity of the ball at t = 1 s?
