The Drop
How much time would a 4 kg ball take to fall 1.5 meters? (Gravity is 10 m/s^2) *

vapour or gas assuming atmospheriv pressure

because growing process had stoped after 4-5 year

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
