  1. Nov 5, 2005 #1
    a car is moving at a constant speed of 11 m/s when the driver presses down the gas pedal and accelerates for 10 s with an acceleratiojn of 1.9 m/s. what is the average speed of the car during the period? I dont know which formula to use inorder to solve it. I tried using vbar= vo + v/2 and vbar= delta X/delta t but its wrong
