Question

PLEASE HELP HURRY a penny dropped out a window reaches a speed of 35 m/s. how far did it fall? initial velocity is 0 m/s and gravity is 9.8 m/s

Answer 1

The height from which the coin fell:

H = 63 m

Step-by-step explanation:

Given:

V₀ = 0 m/s

V = 35 m/s

g = 9.8 m/c²

___________

H - ?

The height from which the coin fell is calculated by the formula:

H = (V² - V₀²) / (2·g)

H = (35² - 0²) / (2·9.8) ≈ 63 m

Answer 2

use v²=u²+2as

v=35

u=0

a=9.8

35²=0²+2*9.8s

1225/2=9.8s

s = 62.5m

answer=62.5m
