I Chapter 1 Section 4 2. In physics, the velocity of a particle,moving with constant acceleration a, with respect to time t, is given by \"em = so + a(t to}, where no and to are the initial velocity and time of the particle, respectively. Consider an object is travelling with a constant acceleration of 2mfsg, whose initial velocity is Im/s and initial time is 33. a) Find the velocity function in the form suit) = all + b. b) Sketch the graph of vhf). 3.
