Vf - Vo = gT

where

Vf = velocity of apple just before hitting the ground

Vo = initial velocity of apple = 0

T = time for apple to hit the ground = 1.5 sec (given)

g = acceleration due to gravity = 9.8 m/sec^2 (constant)

Substituting appropriate values,

Vf - 0 = 9.8(1.5)

Vf = 14.7 m/sec.

pishuonlain [190]

It's a combination of all those things. probably because we are taught from an early age to write in an academic fashion, giving balanced arguments and a conclusion. When speaking from the heart, there is no opposing argument nor is there a conclusion, just emotion.
