Q:
x(t0=(4.0t^2)I+ (2.0t=5)J
where r is meters and t is sec. at what time does graph intersects the x axis.
nvm. i thought about it. y has to be equal to zero.
That isn't the full question right? I cannot understand what you have typed...
this is full questions. its simple. i interpreted the q wrong.
x(t)=(4.0t^2)I+ (2.0t-5)J
