A cargo plane is flyying horizontally at an

altitude of 12.1 km with a constant speed of

1182 km/hr when a large crate slides out of

the rear of the plane.

How long does it take the crate to hit

the ground? The acceleration of gravity is

9.81 m/s

Answer in units of s.

What is the horizontal distance of the crate

from the point it fell off to the point where it

hits the ground?

Answer in units of km.

How far is the crate from the aircraft when

the crate hits the ground, assuming that the

plane continues to y with constant velocity?

Answer in units of km.

An object moving on the x axis with a con-

stant acceleration increases its x coordinate

by 107 m in a time of 2.72 s and has a velocity

of 20 m/s at the end of this time.

Determine the acceleration of the object

during this motion.

Answer in units of m/s2.

my answers are all wrong

What is the time needed for the activity of a radium-226 source to change from 1.5 Ci to 0.50 Ci? The half-life of radium-226 is 1.60 × 103 y.

1.) 2.54 × 103 y

2.) 1.10 × 103 y

3.) 1.60 × 103 y

4.) 5.33 × 102 y

5.) 9.36 × 102 y

Can you please and answer and explain this. Thanks in advance.

I'm a teen New Yorker (from the city) going to Toronto tomorrow night with my mom for six days. Is there any place I should definitely go to, anything really cool that would appeal to a city girl, any food I should eat, or anything of that sort that?

Also is there any advice you guys can give me before I go there?

I have a used 2.5SL 2003 Nissan Altima and when I drive it just shuts off sometimes. When it first started happening I took it for a tune-up and it stopped for a while but then it continued. What's going on with my car? (btw the check engine light has been on for months)

I do not get it at alllll

x= (79,93)

y= (32,28)

z= (86,61)

soo confused :(

y = -65/47x + -740/47

y = 33/54x + 80 5/9

please helpp

I have no clue what a sound barrier is so that would be a great answer too

My friend lives in New York but likes this girl in Oklahoma. He's 18 she's 24. She has a daughter and an ex-husband that "still ruins her life". She once had cancer and has heart problems now. And honestly in a way I kinda think it's all a lie. If someone has soo many health issues, financial issues, plus a daughter to take care of would they find the time to go to California and party it up with numerous guys all the time? He went to Oklahoma to visit her a few months ago and she hardly spent any time with him after he wasted thousands of dollars to get there and buy a hotel room. Actually, when he came back to New York, she broke up with him for good. And no matter what he's still sooo into her. He wants to take her and her daughter to disney for her daughter's birthday. He spent over $70 on a rare flower she likes. And with all of this he's doing for her, she does nothing but complain, ignore his calls and yell at him. And of course this isn't my relationship. Why should I care? but she cursed at me twice which was before I hated her. Like I never said a word to her. And he talks about her daily. She's planning on moving to California and now he wants to move all the way over there to be with her, leaving his family, his college, his whole life in New York. And she's engaged. Should I help him not ruin his life for a girl who doesn't notice he's there or should I leave it alone?

My friend and I are making a website. It's going to be about pretty much anything. It's going to be like a cyber magazine pretty much. And we don't know what to name it. Please help.
