Question:

Miguel drop apile of roof shingles from the top of aroof located 8.52 meters above the ground determine the time required for the shingles to reach the ground

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Answer:

Given:

• The acceleration of shingles is a = g = 9.8m/s²
• Initial velocity (u) = 0m/s
• Distance travelled (s) = 8.52m
• t is the required time for the shingles to reach ground

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Formula used :

$\large\green{\boxed{S = ut +{at}^{2} /2}}$

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

we, get

$\large\orange{8.52 = 0(t) + 0.5(9.8)t²}$

$\large\orange{8.52 = 0(t) + 4.9t²}$

$\large\orange{8.52 = 0 + 4.9t²}$

$\orange{\dfrac{8.52}{4.9} = t²}$

$\large\orange{\sqrt{1.738} = t}$

$\large\red{\boxed{t = 1.318}}$

$\large\red{\boxed{t = 1.32}}$
