Paragraph-Length Response FRO Scrimmage (7 points, suggested time 13 minutes)
A student is experimenting with two constant-velocity carts. The student has each cart travel a distance of 1 meter,
and records the elapsed time for each cart in the table below:
Time for cart to travel 1 meter
Cart A
11.31s
3.075
Cart B
(a) Determine the speed of cart A.
·04m/s

The student then takes the two carts and places them at opposite ends of a track, such that the separation distance
between the front of the carts is 3 meters. At time t = 0, both carts will be released and begin traveling towards each
other.

The carts will collide at position x (measured from cart A's starting position) at time t.
(c) In a clear, coherent paragraph-length response that may also contain diagrams and/or equations, predict the values
of x and 1, the position and time at which the carts collide.
