A dog trainer designed a device to launch a ball into the air for a dog to catch. The device launches the ball when a sandbag is dropped on the lever shown. The trainer wants to be able to launch the ball one meter into the air. Which set of steps should the dog trainer follow to make sure the device launches the ball to the correct height?

• Drop the sandbag. Listen for a sound. Replace the sandbag with something that weighs the same. Repeat all steps until the ball reaches exactly one meter.

• Drop the sandbag. Measure how high the ball reaches. Replace the sandbag with something that has a different shape. Repeat all steps until the ball reaches exactly one meter.

• Drop the sandbag. Add electrical energy to the system. Replace the sandbag with something that weighs the same. Repeat all steps until the ball reaches exactly one meter.

• Drop the sandbag. Measure how high the ball reaches. Adjust the energy of the sandbag by holding it at a different height. Repeat all steps until the ball reaches exactly one meter.
