according to your post, it can be broken down into two times
t=2 and t=8
at t=2 , what I know is x=2A, v=2A, a=A
at t=10, what I know is x=100, v=10 (because v=d/t=100/10, is this relavant?)
there are two eq'ns that come to mind
x(t)= Xi + Vit + 0.5at^2
Vf^2= Vi^2+2a(Xf...
Relevant equations
all kinematic eq'n with x, v, a in it
What I know so far:
I got that x(2)=2A and v(2)=2A
when it comes to b) i have tried various inputs...
Which way do I approach this? Do approach it from x=100 and t=10, do I incorporate x=2A and v=2A.
The closest I've gotten...
A sprinter running a 100 meter race starts at rest, accelerates at constant acceleration
with magnitude A for 2 seconds, and then runs at constant speed until the end.
a) Find the position (relative to the start position) and speed of the runner at the end of
the 2 seconds in terms of A...
