2 cars drag racing question...
The first car has a constant velocity of 40 m/s and moves 10 m before the 2nd car starts moving. The second car speeds up with an acceleration of 3.6 m/s^2. What is the time and the displacesment before the 2 cars actually meet?
V=d/t
d=V1t x (1/2) a t^2.. i think?
I figured out the time it took for the first car to travel 40 m... which would be equal to initial t for the second car. Since I want to find when the two cars have an equal displacement i set their displacements equal and it didn't really work out cause i ended up with a negative time for some reason?
