Mathematics
1 answer:
Leya [2.2K]3 years ago
5 0

Answer:

2.04 seconds

Step-by-step explanation:

Falling objects near the surface of the earth have an acceleration of -9.81 m/s².

Acceleration is the change in velocity over change in time:

a = (v − v₀) / t

-9.81 = (-30.0 − (-10.0)) / t

-9.81 = -20.0 / t

t = 2.04

It takes 2.04 seconds.

$36 if it's an annual rate. If it's a monthly rate it's $432

Step-by-step explanation:
