To solve the problem of how soon the shell launched from the cannon will reach the target, we can follow these steps: ### Step 1: Convert the distance to meters The distance between the cannon and the target is given as 5.10 km. To work in consistent units, we convert this distance to meters: \[ r = 5.10 \, \text{km} = 5.10 \times 1000 \, \text{m} = 5100 \, \text{m} \] ...
