Answer:

3.61 m/s²

Explanation:

Given:

v = 12 m/s

x = 7 m

x₀ = 0 m

t = 6 s

Find:

a

x = x₀ + vt - ½ at²

7 m = 0 m + (12 m/s) (6 s) - ½ a (6 s)²

a = 3.61 m/s²

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

Ket [755]

Hello! :)

$\large\boxed{19.6 m}$

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

$d = \frac{1}{2} at^{2}$

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:

$d = \frac{1}{2} (9.8)2^{2}\\\\d = \frac{1}{2} (39.2)\\\\d = 19.6 m$
