Verdah, Hetav and Dhinesh are undertaking an investigation into the motion of wooden blocks in their Physics class. Their aim is to determine the effect that mass has on the horizontal motion of the wooden block across a table. Verdah suggests that they use a launcher to give both blocks the same initial velocity and that they use the same table for each trial.

The blocks are made from the same wood but have different masses. The mass of block A (m1) is twice the mass of block B (m2). The coefficient of friction between the blocks and the table is u.

A. Derive a mathematical expression that the students could use to find the distance block A travels after it leaves the launcher. Upload a copy of your HANDWRITTEN working clearly identifying all equations and constants used in your derivation. Make sure your name is visible next to your working.
