Question

Speedy Sue, driving at 32.0 m/s, enters a one-lane tunnel. She thenobserves a slow-moving van 155 m ahead traveling with velocity 5.40m/s. Sue applies her brakes but can accelerate only at -2.00 m/s2because the road is wet. Will there be a collision?

yes

no


If yes, determine how far into the tunnel and at what time thecollision occurs. If no, determine the distance of closest approachbetween Sue's car and the van and enter zero for the time.
distance m

time s

i seem to understand it very well, i know they collide but imjust stuck on what exactly im supposed to jot down as theanswers.
