t is in seconds and the coefficients have the proper units for the vector r to be in meters.

1. Find velocity vector v(t) and acceleration vector a(t) of the particle.

Answer: v(t)= 3.0 i+4.0t j

a(t)=4.0 j

2. Find the magnitude and direction of v(t) at t=1.0second

Answer: 5.0 m/s

theta=53 degrees with xaxis

I want ALL the steps.Please.

Thanks

with a speed of 90kmph.Calculate 1.Veloctiy of B with respect to A

3.Velocity of a monkey which is running on the roof of A against its motion with a velocity of 18kmph with respect to A as observed by a man standing on the ground.

Answer= 10m/s

Please solve it in all the ways it can be solved.Thanks a lot... :)

(i) 53 x 10^ -10 cm (10 to the power of -10)

(ii) 53 x 10^ -12 m

(iii) 53 x 10^ -3 nm

(iv) 53 x 10^ -6 micron

I think they're wrong.If they're correct please explain why.

Thanks a lot

I just read what all could happen if I didn't maintain hygiene and wasn't careful with them and my heart totally sank.I'm fed up of wearing spectacles.Also they've somewhat scarred the skin on my nose.I read a LOT and until now haven't been very responsible in everything.I cry very often.Is there anyone who's been wearing lenses from a long time and thinks it is manageable? Should I start wearing them?

besides locking the main door of the house.Since they didn't want me to shut them out and be alone in my room even for a moment,when they were in the house, they used the same lock on the doors of the house to ensure that I couldn't do it and hide the keys.The unfairness of it all-always restricting me to stay in the house when I'd done nothing wrong, just because I'm a girl-made me so angry that I somehow broke one of the locks,found the keys for the others and hid them in different places.But they eventually found the keys and started imprisoning me again.Finally when I could stand no more,after a few months,I found them again and threw some with organic waste and others on the street.Now,the situation is a little better-they're not that mean to me,I can use the internet and be alone in my room-and as we're changing our residence,they say that they're going to need those keys for their limited valuables to not get stolen.I agree and they're running low on money and don't want to buy new ones.They're badgering me to give them back.Should I tell them the truth,"You caged me like an animal those days,didn't you? So I just threw them"? Or should I let them frantically search all over the house and waste their time because the other one will seem provocative to them to make my life hell no matter how I rephrase it? I really think that they deserve it but..I don't know what to do.Please pardon my English.

I don't have much knowledge regarding this stuff. I have a WiFi device,have downloaded a virtual WiFi router and have made my computer a WiFi hotspot. I found

my pc's name after i scanned for available WiFi networks in my tv, entered the password and tried to connect it but couldn't.

It shows a message saying 'Router not found' .

Please don't tell me that I've to buy a real wifi router because I can't afford it.There has to be some other way...I've downloaded a virtual router as i said...so why is it showing that message and how do i connect it to my pc's internet successfully?? Please help....

Thankyou in advance....
