Assessment; 1. What does Newton's second law of motion say about the relationship among force, mass, and acceleration? 2. Who is the proponent of Newton's second law of motion? 3. The force of an object is directly proportional to the acceleration of the object. 4. Juan pushes ball A as hard as he can. Jose exerted the same amount of force that Juan used to move ball B, which has twice the mass of ball A. Ken used only half the force that Juan used to move ball C, which has twice the mass of ball B. Which ball will have the greatest acceleration? 5. Zach throws a baseball with a mass of 0.145kg, exerting a force of 50N. Using the Newton's second law of motion, what is the ball's acceleration? (Round off your answers to the nearest whole number.) 6. Mark picks up a medicine ball that has a mass of 12kg. He then applies 15N of force to lift the medicine ball. What is the acceleration of the medicine ball in ms²? Note: Please do not input the the unit of measure. 7. Jay has a football with an undetermined mass. He throws the ball with a force of 50N. He is standing on a football field so he is able to figure out the acceleration of his throw using the markings on the field. Therefore, he knows that the ball travelled with an acceleration of 25ms2. What was the ball's mass in kilograms? 8. Jenny and Camille are playing catch with a softball that has a mass of 0.5kg. Jenny throws the ball with a force of 20N, while Camille throws the ball with a force of 30N. What is the difference in acceleration between Jenny's toss and Camille's toss? 9. Candy is driving a car along a highway. She checks on the speedometer and it reads a=60m/s for 30 seconds. If the mass of the car is 80kg, what is the net force acting on the car? 10. There are three boxes on the top of a ramp. Box A has a mass of 3kg, Box B has a mass of 2kg, and Box C has a mass of 5kg. When pushed, all three boxes moved with the same acceleration. Arrange the boxes in order of decreasing net force.
Why did one group have a placebo injected before being exposed to the virus? A. They were part of the control group. B. They were part of the experimental group. C. They would be protected from the disease. D. They would exposed to a weakened form of the virus
