Question

A car is initially moving with a velocity of 3 m/s. then it accelerates uniformly at the rate of 0.6 m/s^2 for 5 seconds. What is the distance traveled by the car in 5 seconds?

Answer 1

\[s = V_o*t + \frac{1}{2}*a*t^2 \]

Answer 2

ahhh I dont understand this stuff.

Answer 3

\[s = 3 \times 5 + \frac{1}{2}\times 5^2 \times .6\]
\[s = 15 + \frac{1}{2}\times 25\times \frac{6}{10}\]

Answer 4

this will give me the distance?

Answer 5

I don't understand it either but I keep practicing, you must practice and keep trying; you will understand all this soon.


Yes, It will

Answer 6

i am seriously behind. like my labs, I am like 6 weeks behind >.< due to not understanding! would you mind helping me with my quiz?

Answer 7

I will try my best!

I am so behind too only 5 months left and I have to complete Mechanics, Thermodynamics, Optics, Electrostats and Modern Physics, Life hits you hard sometime

Answer 8

22.5

Answer 9

holy crap kidddo! :) you very sciencey...not a word, i know.. but WOW! I would really appreciate teh help :)

Answer 10

bharatindians! That was right!!! Thank you :))

Answer 11

if u have problems simple concepts then try this dear.. that will really helps u..

Answer 12

so thevertical is position(x) and horizontal is time (sec) its asking if it represents uniform velocity, unirform accerleration, the objesct is at rest , or its accelerationg and decelerating..I have no idea?

Answer 13

HELP! PLEASE!?

Answer 14

http://www.khanacademy.org/ that's really help u in ur studies

Answer 15

accelerating according to me

Answer 16

thats what i thought, nbut idk what any of the uniform ones mean or what not :/

Answer 17

oh wait it must be uniform acceleration

Answer 18

:) imma just post the quiz stuff here kay?

Answer 19

the graph is position time I assumed it as velocity time silly me sorry it must be uniform acceleration


yeah it's fine with me

Answer 20

What does the area under the velocity-time graph represent?
(Points : 1)

acceleration


displacement


speed


velocity

Answer 21

displacement, pretty sure this time

Answer 22

i said volcity :/

Answer 23

oh my bad =P

Answer 24

An object is thrown with an initial velocity of 3 m/s. What is its acceleration at its maximum height?
(Points : 2)

zero


3 m/s2


9.8 m/s2


none of the above

I saidzero :/

Answer 25

umm I think it's 9.8

Answer 26

Gravity Works all the time
