Question

After your patched the roof, you dropped the hammer off the house and you heard it land on your toolbox on the ground 3.3s later. What is the height of the house ?

Answer 1

53.36 m.

Step-by-step explanation:

Initial velocity of the toolbox u = 0

acceleration due to gravity g = 9.8 m s⁻²

time t = 3.3 s

height of roof h = ?

h = ut + 1/2 g t²

= 0 + .5 x 9.8 x 3.3²

= 53.36 m.
