Question

If a ball rolling in a straight line decelerates at a rate of 4 m=s starting with velocity 8 m=s then how far has the ball traveled after 2 s

Answer 1

google it , yahoo answers

Answer 2

or try to do 4 *8 i would tell you if i new sorry :/

Answer 3

for a uniformly accelerated / decelerated motion,
you should know the following equations
\[v ^{2}=u ^{2}+2ax \]
\[x=ut +\frac{ 1 }{ 2 }at ^{2}\]
\[v=u +at\]

Answer 4

v=final velocity
u=initial velocity
a=acceleration / deceleration
t=time taken
x=displacement
