Jonas and his family are moving to another part of the city. As Jonas, his brother, and his Dad were driving one of the trucks filled with furniture to their new home, the truck ran out of gas. A gas station is 0.5 miles down the road. The three of them decide they need to somehow get the truck to the gas station to get gas. Jonas tries pushing the truck, but can not make it move. Which of the following would NOT be a solution to help get the truck to the gas station?


Unload the furniture out of the truck. With less mass, they should be able to push the truck to the gas station.

Jonas and his brother push the truck. With more force, they should be able to push the truck to the gas station.

Jonas’ brother gets out of the cab of the truck and sits in the back of the truck with the furniture. With less mass, they should be able to push the truck to the gas station.

Unload half the furniture out of the truck and let Jonas and his brother push. With less mass and more force, they should be able to push the truck to the gas station.
