As a pickup truck (total mass of 2500 kg, including fuel and driver) approaches a rise in an otherwise flat road, the driver presses the clutch and begins to coast. Initially the truck was moving at 34 m/s. For many reasons, including friction losses, the truck has slowed to 10m/s upon reaching the top of the rise (the change in elevation was 25m). What was the total change in the mechanical energy of the truck in kJ? (Hint: it will be negative.)
