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

I really want to lose about 25 pounds before I go on a trip this summer. Its about 4 months away. Is there any hope that I can meet my goal? I just started working out twice a day and I have already cut out all soda and junk food. Any other ideas?
Well, I’ve heard about this last year (June 6,2006, 6/6/06) lol not really 666. But, anyway… I’ve also heard many cultures have predicted our so called “dooms day”. One thinks it is sometime in May,2012. Also, in the Catholic bible, it predicts this day when the ‘Beast’ with the markings 666 will kill us all. I know this is a very um, I guess bleak putting it easily. But, I am curious what other cultures predict, if they do at all. I know this is a weird question to ask, I hope you won’t get offended or anything.>Thanks
ok friday my substitute teacher for science thought she caught me cheating but she really didn’t all i was doing was helping my friend out by checking his answers with mine but my sub thought i was given him answers and so she took my paper and is probably gonna email my teacher saying i was giving my buddy answers and then my actual teacher is probably gonna get me suspended for like 3-5 days cause my school is kinda strict on that stuff but hats not really the point my point is my parents are gonna get flaming pissed and most likely gonna believe me cause for some reason they don’t believe a lot of stuff that comes out of my mouth i don’t know why but they don’t but my dad is gonna get really pissed at me probably and its probably gonna escalate to where he’ll kick me out of the house which he has done before but all i do is go to my friends house for like the rest of the day and come home the next day this has happened like at least 30 times but im thinking if he tells me to get out i think i might leave for good like runaway im 14 years old i have like $220 saved up and i live in california and i have a lot of survival skills i go camping like every weekend down at river during summer and since i lived in san francisco till i was like 11 i have a lot of street wise to but now im living in a small town in northern california and if i leave i might find my way over to a small town about 3 hours out of little rock arkansas where all my cousins and uncles and aunts live basically and my last name is known big time in that part of the state but i don’t know should i really run away or should i just deal with my parents
oh yeah and also right know i have a sprained wrist and if i do runaway i will be running away from a lot my parents have given me a lot and i appreciate that but its just my dads got a temper a real bad one but he doesn’t hit me he just makes his problems disappear
