Answer to Question #67253 in Mechanics | Relativity for Kaitlin Esty

Question

If your front lawn is 25.0 feet wide and 20.0 feet long, and each square foot of lawn accumulates 1050 new snow flakes every minute, how much snow (in kilograms) accumulates on your lawn per hour? Assume an average snow flake has a mass of 2.00 mg.

Answer 1

S = 25.0 x 25.0 = 625 sq feet

Number of snowflakes accumulated on the lawn every hour:
N = 1050 x 625 x 60 = 39375000 snow flakes
m = 39375000 x (2.00/1000000) = 78.75 kg
