Question

A ball is thrown horizontally from a height of 30 m. with an initial velocity of 20 m/s. a) How far will it travel after 10 secs.? b)What is its vertical velocity?

Answer 1

a) The horizontal distance of the ball will be

$$d=v_xt=20·10=200\text{ m}.$$

b) The vertical velocity will be

$$v_y=gt=9.8·10=98\text{ m/s}.$$
