The ball's velocity at the bottom of the hill can be found using the equation:v = u + atwhere:v is the final velocityu is the initial velocitya is the accelerationt is the timeSubstituting the given values into the equation, we get:v = 4.0 m/s + (1.4 m/s^2) * 4.0 sv = 4.0 m/s + 5.6 m/sv = 9.6 m/sTherefore, the ball's velocity at the bottom of the hill is 9.6 m/s, which is closest to choice D) 10 m/s.
