a ball is thrown vertically down towards the ground with an initial velocity of 4.23 m/s the ball falls for a time of 1.51 s before hitting the ground. Air resistance is negligible.
a) show that the downwards velocity of the ball when it hits the ground is 19.0 m/s.

matt101 · Answer

You can calculate final velocity using the following equation:

$$a=\frac{v_f-v_i}{t}$$
