# Tractor

**Classical Mechanics**Level 5

A tractor moving forward at uniform speed on a horizontal ground has a front wheel diameter of \(0.8\text{ m}\) and back wheel diameter of \(1.25 \text{ m} \). The horizontal distance between the axles of the two wheels is \(2\text{ m}\). During a trip a pebble stuck to the front wheel flew off the wheel at the highest point. 0.2 second later, another pebble flew off the back wheel at its highest point too. The two pebbles landed on the same spot on the ground. Find the speed of the tractor in \(\text{m/s}\).
