Homework Statement
A child stands 30m behind an ice-cream truck. The child then runs towards the truck at a constant velocity of 5m/s. At that moment, the ice-cream truck accelerates at 1m/s^2 from rest to drive away from the child. Does the child catch the ice-cream truck?
Homework Equations
Δd=v(initial)t-1/2∂Δt^2
d=(vf+vi)/2*t
vf=vi+at
d=(vi)t+1/2at^2
vf^2=vi^2+2ad
d=(vf)t-1/2at^2
v=Δd/Δt
∂=v/Δt
The Attempt at a Solution
Bearing in mind that I had to solve for time, I made the assumption that if the two objects met, their times would be the same (t1=t2). However, I'm not sure how to approach this question and I'm very new to these types of problems; any help is appreciated.
Thanks in advance :)
