Unit 1- Physical Laws

George’s car, which has a mass of 1,200 kg, is out of gas. He is pushing the car to a gas station at an acceleration rate of 0.3 m/s². Across town, Ringo’s car battery has died and he is pushing the car out of the road. If he uses the same force as George, but has a rate of 0.2 m/s², what is mass of Ringo's car?

• 1500 kg
• 2000 kg
• 1200 kg
• 1800 kg

John manufactures medical supplies. He wants to test the pressure inside a syringe that his company sells. When the syringe is at a volume of 3 cm³, the pressure inside is 5 lbs/psi. How much pressure is inside the syringe when the volume is 12 cm³?

• 1.25 lbs/psi
• 0.5 lbs/psi
• 3 lbs/psi
• 10 lbs/psi

A science class conducted an experiment and found that a force of 3 Newtons will stretch a spring by 6 meters. What is the force needed to stretch the spring 12 meters?

• 4 Newtons
• 8 Newtons
• 6 Newtons
• 10 Newtons

Which law should you use?

George’s car, which has a mass of 800 kg, is out of gas. He is pushing the car to a gas station at an acceleration rate of 0.5 m/s². Across town, Ringo’s car battery has died and he is pushing the car out of the road. If he uses the same force as George, but has a rate of 0.8 m/s², what is mass of Ringo's car?

• Newton's 2nd Law

• Boyle's Law

• Hooke's Law

John’s car has a mass of 2500 kg and is out of gas. He is pushing the car to a gas station at an acceleration rate of 0.8 m/s2. Across town, Ringo’s battery has died and he is also pushing his car out of the road at a rate of 0.2 m/s2. If both John and Ringo use the same force, what is the mass of Ringo’s car?

• 1500 kg
• 5000 kg
• 3000 kg
• 10000 kg
