25. At time t = 0, a car has a velocity of 16 m/s. It slows down with an acceleration given by -0.50t, in m/s^2 for t in seconds. At the end of 4.0 s it has traveled:

26. At time t = 0, a car has a velocity of 16 m/s. It slows down with an acceleration given by -0.50t, in m/s^2 for t in seconds. By the time it stops it has traveled:

27. Starting at time t = 0, an object moves along a straight line with velocity in m/s given by v(t) = 98 - 2t^2. where t is in seconds. When it momentarily stops its acceleration is:

28. Starting at time t = 0, an object moves along a straight line. Its coordinate in meters is given by x(t) = 75t - 1.0t^2, where t is in seconds. When it momentarily stops its acceleration is:
