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.
Answer:
i think the answer would be: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.

Explanation:
A basketball with a mass of 0.80 kg is accelerated with a force of 16.0 N. If resisting forces are ignored, what is the acceleration of the basketball to the nearest m/s2?
Answer:
Acceleration = 20 m/s2
Further explanation:
16 N = 0.80 kg x acceleration
Acceleration = 20 m/s2
A heavy box is dropped from the roof of a small building and is traveling to the ground. Which claim about the forces acting on the box must be true?
Choose 1 answer:
A. There are no forces on the box.
B. There is no net force on the box.
C. There is a net force on the box.
D. There is not enough information.
Answer:
C. There is a net force on the box.
Explanation:
If the box was stationary, sitting on the roof, the correct answer choice would be A. In this scenario, the box is fallign downward, meaning that there is a net force pushing the box downward.
Answer:
C: there is a net force on the box

Several objects were dropped from a balcony. Using the data below, determine which statements must be true regarding the rate of force of each falling object. Neglect (ignore) air resistance. Object Mass Diameter Height of drop Tennis Ball 0.06 kg 6.6 cm 5 m Baseball 0.15 kg 74 cm 5 m Bowling Ball 5 kg 21 cm 5 m Golf Ball 0.04 kg 4.3 cm 5 m Statement 1: All balls hit the ground at the same time Statement 2: All balls hit the ground with different forces Statement 3: The bowling ball hit the ground first and the tennis and golf ball hit the ground last Statement 4: It is not possible to tell how much force each ball hit the ground with
Answer:
statement three and statement 2
Explanation
since they are weighted different, they will have more or less force (more mass=more force), also the heavier an object, the greater its acceleration while falling.
