Anonymous, how would I enter that in the boxes?....see below thanks
thanksThe velocity of a subatomic particle moving through space can be modeled by
v(t)=0.1t^2 −2t +0.2
for t≥0 where t is time in seconds and v is velocity in m/s.
Find the following:
a) (a) The time(s) t at which the particle is not moving:
......... and .........
b)The interval(s) over which the particle is moving forward: (Remember to write union as U and infinite as INF) ..................
c)The interval(s) over which the particle is moving backwards: (Remember to write union as U and infinite as INF) ..................
Thanks!
I know A is The time(s) t at which the particle is not moving: 0.10 and 19.90
I know B is [0, 0.10) U(19.90, INF)
But:
I thought C would be (-0.10, 19.90) but it says wrong..
Thank you

The equation is only applicable at positive t.
-0.10 is not allowed
0.10 < t < 19.90 is when it is in reverse

Anonymous, how would I enter that in the box...(I think there are two numbers which need to be separated by a comma)
thanks
