<u>Change</u> of PE over a height of 10m = M G H = (10) (9.8) (10) = 980 joules.
When the box hits the bottom, it has 980 joules <u>less</u> PE than it had
before it started dropping.
(As well as 980 joules <u>more</u> kinetic energy.)
The distance between (-22,15) and (30,-25) is 4√269 ≈ 65.6
Yes, he is correct, using the distributive property you get the same answer
Answer:
3/8 of the day
Step-by-step explanation:
A day is 24 hours
You spend 9 of them sleeping
The fraction you spend sleeping is
