Okay I suck at physics and if someone could help me out it would be greatly appreciated.(adsbygoogle = window.adsbygoogle || []).push({});

- A ball is projected horizontally from the edge of a table which is 0.8 m high, as shown below. The ball lands 0.2m from the table

- How long does the ball take to fall to the ground?

Worked it out to be 0.4s using s = ut + 1/2 at^2

0.8m = 1/2 * 9.8t^2

1.6/9.8 = t^2

t=0.4s

- Hence show that the ball was projected with a horizontal speed of 0.5ms

but whenever I work this out I get 4m/s. :(

v = u + at

v = 9.8 * .4

v = 4m/s

Dont think this place is really for Secondary level Physics but I couldnt find anywhere else
