Question

If you were to drop a rock from a tall building, assuming that it had not yet hit the ground, and neglecting air resistance. What is its vertical displacement (in m) after 8 s? (g = 10 m/s2)

Answer 1

320m

Step-by-step explanation:

The vertical displacement is given by:

`y_0-y=(1)/(2)gt^2-v_0t`

Assuming v₀=0, t=8:

`y_0-y=(10)/(2) * 8^2 + 0* 8 = 320`
