A drone sends a radar pulse vertically downwards over a forest. Part of the pulse reflects from the top of the tree canopy and the rest reflects from the ground.
The radar pulse travels at 3.0 × 108 m/s. The echo from the tree canopy returns after 0.80 μs0.80\ \mu\text{s}0.80 μs. The echo from the ground returns after 1.0 μs1.0\ \mu\text{s}1.0 μs.
Calculate the height of the tree canopy above the ground.
