Asteroid: Calculate the change in the length of a day due to the impa?

Suppose an asteroid of mass 6e20 kg is nearly at rest outside the solar system, far beyond Pluto. It falls toward the Sun and crashes into the Earth at the equator, coming in at an angle of 30 degrees to the vertical, against the direction of rotation of the Earth. It is so large that its motion is barely affected by the atmosphere.

Impact Speed: 43474.4226

Calculate in hours the change in the length of a day due to the impact: ????

I have been trying this equation and solving for T and have gotten wrong answers each time:

-sin(theta)*R_1*M_a + 2/5*M_e*R_1^2*(2pi/8.64e4) = 2/5M_e*R_1^2(2pi/T)

R_1: 6.4e6
M_e: 6e24
8.64e4 = how many seconds in an hour
yes sorry!!!!! its supposed to be -sin(theta)*R_1*V_impact*M_a + ………

ugh i cant believe i left that out
Also, I only have one submission left for my HW so if anybody can back the first answer up that would be fantastic

What kind of person do you think i am?

I’m a girl, wear tshirst, shorts or jeans, chin length hair that’s wavy, im slight under weight but i am working on that, i get dirty on an average day, not very sporty but into wildlife survival skills, likes animals, working on my rock climbing skills even thought i can climb a tree bare in under 10 seconds. what would you say?
*bare foot* sorry my bad.

I’d like to become more useful…?

Hello. Apologies for the length of this in advance.

I’ve recently become a fan of the show “The Colony” on The Discovery Channel. After watching several episodes, I’ve become disparaged as to what my own usefulness would be in such a situation. If you don’t know, The Colony takes a sample of people and puts them together into a situation which attempts to simulate what an apocalyptic event would be like. In other words, they have no electricity, amenities, tools, etc. They attempt to survive by putting together shelter, establishing order, guarding against looters, etc.

I’ve been reading discussion groups on this with people stating various things they would do which range, from killing people and looting strangers, to rebuilding society. I however, am not sure what I would do.
I’m not a completely pampered city boy; I live out in the country and I’ve built small standing buildings like sheds and such with my dad, but I’ve only been the sort of mindless builder, cutting wood, and nailing whatever I’m told to do. I have no skill for designing or engineering of the sort, my interest in life has been in arts and literature. The show includes people like contractors, engineers, mechanics, etc. I am amazed by the skills these people possess, and wish I had the same sort of qualities. Unfortunately, I can’t even change oil (not that I’ve ever had need to though, I don’t drive or have a car).

I love the show, but watching it always leaves wishing I knew the survival skills they display. They hunt, they design and build shelters with defenses against intruders, they even create rudimentary technology like light systems, am transmitters, and generators, all from spare parts.

I was wondering what the best way would be to go around learning these awesome skills. I’m going to be senior this year in high school, so hopefully there is still a lot of time for me to learn.
I’m sorry if this is posted in the wrong place.

Also, I feel I should mention that i’m thinking of going the medical route in my career life, because of this very problem. I feel that medicine is an important skill, but i’d like to become useful in other ways as well.

Another Escape The Fate’s song Called “My Apocalypse”. Lyrics: There’s a place that I’ve found As far as I can see This place lies within The depths of my dreams In a garden surrounded By fire and trees Through the smoke a silhouette I can barely see There’s a man with an axe Standing in the rain Looked me straight in the eyes This is what he had to say Never fall asleep You won’t wake up Destroy the guillotine Before he does I walk with shadows (you have to find a better way) I walk with shadows (the questions I will never say) Hiding from the gallows (they keep me safe and sound) So I walk with shadows (the ways of burning down this house) End transmission The satellites are down I need an earthquake To shake this pity OFF THE GROUND Just don’t trust these liars at the door (you have to find a better way) Kill the ones that have these answers for (the questions I will never say) Never fall asleep You won’t wake up Destroy the guillotine Before he does I walk with shadows (you have to find a better way) I walk with shadows (the questions I will never say) Hiding from the gallows (they keep me safe and sound) So I walk with shadows (the ways of burning down this house) End transmission The satellites are down I need an earthquake To shake this pity Off the ground All the vibrant colors I see And the shades that fill the grey Pain The pain Pain The pain Pain the pain Pain [x2] Hiding from the gallows (you have to find a better way) I walk with shadows (the questions I will
