Beginner PHYSIC problem HELP nneded

In summary, two train cars are on a horizontal track with one starting at rest and the other moving at a constant speed. The first car has a constant acceleration of 2.4 m/s2 and is approaching the second car, which is 29 m away and moving at 4.0 m/s. The questions are where and when the cars will collide. To solve this problem, the kinematics equations can be used and a negative sign should be placed in front of the second car's velocity.

Homework Statement



Two train cars are on a straight, horizontal track. One car starts at rest and is put in motion with a constant acceleration of 2.4 m/s2. This car moves toward a second car that is 29 m away and moving at a constant speed of 4.0 m/s.

a.) where will they collide
b.) how long will it take to collide

Homework Equations





The Attempt at a Solution


My original plan to solve this problem was to set up two separate Kinematics equaitons .
I also put a negative sign infront of - 4.0m/s. My answer came out like 8.743 s .

ANY HELP OR ANY ADVICE WOULD BE GREAT
