A ball of mass m1 and a block of mass m2 are attached by a lightweight cord that passes over a frictionless pulley of negligible mass, as shown in the figure below. The block lies on a frictionless incline of angle θ. Find the magnitude of the acceleration of the two objects and the tension in the cord.
Let's solve this problem using Symbolism, a computer algebra library for C#.
Free-body diagram for the ball:
| 1. Make an empty file named "direct.gps" in a MicroSD(HC). | |
| 2. Make a file named "gps.cfg" in the MicroSD(HC) with containing the following binary (printed in hex format). | |
| B5 62 09 01 10 00 C8 16 00 00 00 00 00 00 97 69 21 00 00 00 02 10 2B 22 | |

| (This information depends on GPS receiver firmware version. please see http://wiki.openstreetmap.org/wiki/UbloxRAW) | |
| 3. Insert the MicroSD(HC) to NinjaScan-Light and power-on. NinjaScan-Light will be recognized as COMx. | |
| 4. Configure RTKLIB input; Rover from Serial type via COMx and u-blox format. |
