    Answer:

    Explanation:

    This is a classic acceleration problem in one dimension. Use the equation

    a=\frac{v_f-v_0}{t} where a is the acceleration of he car, vf is the final velocity (and our unknown), v0 is the initial velocity, and t is time in seconds. Filling in:

    2=\frac{v_f-22}{7} and

    14 = vf – 22 and

    36 = vf (not quite right with the sig dig’s but I’m guessing you’re not really into the specifics much, judging by the acceleration and the time values)
