Homework Statement
Two objects A and B are moving in opposite directions toward each other in one dimensional motion along the east-west (-X, +X) line. Initially they have velocities of equal magnitude, 3.00 m/sec, with the first particle subject to a uniform acceleration of 2.00m/sec
2 directed in the positive +X direction and B, which is 20.00 meters away in the +X direction from A, is subject to a uniform acceleration of 1.00 m/sec2 directed in the -X direction.
Homework Equations
Obtain the distance from the initial position A of the first object and the direction of the point where they meet and the time t at which the meeting occurs.
The Attempt at a Solution
For object A I wrote: x = 3t + t2
For object B I wrote: 20 - x = 3t + .5t2
I followed my professor's example and I cross multiplied but that doesn't work here. In the problem my professor did the initial velocities were set to 0, so cross multiplying worked. Can anyone help me?
