Question

a one kilo stone falling freely from a height of 10 m , strikes the ground with a velocity of​

Answer 1

Answer:

let us first find time,

h = 10m

g = 10m/s (we use 10 for easy calculation)

so, h = 1/2gt^2

10 = 1/2 *10 t^2

2 = t^2

t = √2 sec

we know, v = gt

v = 10(√2)

therefore, v = 10√2 m/s

Answer 2

Answer:

Explanation:

h=10m

g=10m/s^2

u=10m/s

Using kinematics equation for a falling object:

v^2-u^2=2gh

v^2-0=2*10*10

v^2=200

v=√200

v=10√2 m/s
