Question

as the shuttle bus comes to a sudden stop to avoid hitting a dog, it accelerates uniformly at -4.1 m/s2 as it slows from 9.0 m/s to 0 m/s. find the time interval of aceleration for the bus.

Answer 1

\[a=\frac{2d}{t^2}\]

Answer 2

nt exactly a question for math forum
use speed time equations
v=u+at
s=ut+0.5at^2
or v^2=u^2-2as

Answer 3

\[v^2=(v_o)^2+2ad\]
still not quite right lol
\[v=v_o+at\]

Answer 4

therefore:\[t=\frac{v_f-v_i}{a}\]

Answer 5

Im still confused..
