Question

stone thrown from a tower at an horizontal inital rate of 20 m/s . Determine the speed and normal acceleration of the stone ?

Answer 1

is this a complete question?

Answer 2

yes, if the experiment is made in the Earth (or a planet).
the stone will continue to have 20 m/s of horizontal velocity (neglecting any influence of air) and about 10 m/s2 of vertical acceleration (on the Earth).

Answer 3

9.8 m/s^2

Answer 4

vertical speed 20 m/s

Answer 5

vertical speed 20 m/s

Answer 6

vertical speed 20 m/s

Answer 7

well, that could be 20m/s and 9.81m/s^2 if it is on EARTH
