Question

A stone is dropped from height of 10 m on an unknown planet having g= 10 m/s2.calculate the velocity when it hits the surface of the planet. Also calculate the time its take to fall through this height ​

Answer 1

Answer:

14.14 m/s

Explanation:

h = 10m, g= 10m/s², u= 0, v=?

v² - u² = 2gs

v² - 0 = 2 x 10 x 10

v² = 200

v = √200

v = 14.14 m/s
