A football player, starting from rest at the line of scrimmage, accelerates along a straight line for a time of 1.5 s. Then, through a negligible amount of time, he changes the magnitude of his acceleration, he continues in the same direction for another 1.2 s, until he reaches a speed of 3.4 m/s. What is the value of his acceleration (supposed to be constant) through the initial 1.5 s period?
