An apple is dropped from the top of a building and hits the ground 2 seconds later. How tall is the building?

Hello! :)

Use the kinematic equation below to solve for the height of the building:

Where:

d = distance, or height of the building (m)

a = acceleration due to gravity (9.8 m/s²)

t = time (seconds)

Plug in the given values into the equation:

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
