Question

find the answer of science class -9 ​

Answer 1

Answer:

a) THE TIME TAKEN = 0.5 SECONDS

ACCELERATION DUE TO GRAVITY =10M/S

INITIAL VELOCITY =0m/S

USING THE 1ST EQUATION OF MOTION,

THAT IS, v=u+at

v=0+10(0.05)

v=0.5

Therefore, the speed on striking the ground is 0.5m/s

c)Using the equation,

s=ut+1/2at^2

s=o(0.05)+1/2(10)(0.05)^2

s=0+5(0.25)

s=1.25m

Ï am somewhere wrong in calculations do correct it.

and yeah overall the method will be like this.
