I have no idea how to answer this after I've spent many minutes trying.
A particle is moving along the parabola y = x^2 - 5x - 6 such that the x-coordinate of its position at time t is a linear function of t, i.e.:
x = a(t) + b for some constants a and b.
If, at time t = 2 the particle is at...
Particle travels from t=0 to t=4 along curve:
x=(t^2)/2
y=(1/3)(2t+1)^1.5
0<or equal to t <or equal to 4
At what point (x,y) has the particle covered 1/2 the length of the curve?
please show all steps
