Welcome back JNR — missed you this week. Step 1: Formulate the relationship between total mechanical energy (E), potential energy (P), and speed (V). The problem states that the total mechanical energy E varies partly as the potential energy P and partly as the square of the speed V. This can be written as: E = k_1 P + k_2 V^2 where k_1 and k_2 are constants of proportionality. Step 2: Use the given scenarios to set up a system of linear equations for k_1 and k_2. Scenario 1: When V = 8 \, m/s, $P = 125
