Question

A bus is moving at 22m/s [E] for 12s. Then the bus driver slows down at 1.2m/s/s [W] until the bus stops. Determine the displacement of the bus.
Given: V1: 22m/s [E], V2=0, a= -1.2m/s/s [E], t=12s

Answer 1

i got an answer of 177.6m but it says the answer is
4.7x10^2m

Answer 2

E=positive and W=negative

Answer 3

mhm

Answer 4

the second part:

Answer 5

yup

Answer 6

\(v_0 =22m/s,~~v=0~~a=-\dfrac{1}{2}m/s^2\) by \(v^2 = v_0^2 + 2aS_2\) you can find out \(S_2\) right?
add \(S_1 +S_2\) you get the answer from the book

Answer 7

i got 481.6m now

Answer 8

would that b right still?

Answer 9

why? I got 465 .66 m. So, if take 2 sig.fig. you have 4.7 x 10^2 as you stated

Answer 10

oh wait nvm i forgot to add 264 lol sorry im really tired atm

Answer 11

i got it thanks :))))
