How fast is a ball going when it hits the ground after being dropped from a height of 16m The acceleration of gravity is 9.8ms2?

The speed of the ball can be found using the kinematic equation: final velocity (Vf) = sqrt(2 * acceleration * distance). Plugging in the values, Vf = sqrt(2 * 9.8 * 16) = sqrt(313.6) ≈ 17.7 m/s.
