Section 4.3 introduces us to Newton's 2 o Notice that there is really no need for the 1" Law, since it is a special case of this 2" 1 Law. Equation One special trick check out equation 4.7. Pay special attention to the definition of weight. Weight is a force and is different from mass. 1. A rocket is accelerating on the surface. Name the four types of forces that act on the rocket. Draw a free body diagram. 2. A coffee filter is dropped. This is falling straight down toward the floor. Name the two forces acting on the coffee filter. What is the direction of each of these forces? Draw the free body diagram. 3. A box weighing 800N is dragged across a level floor at a constant speed (what does this mean about the acceleration?) Draw the free body diagram. [There should be 4 forces acting on this box.] What is the magnitude of Fret ? 4. The engine of my Journey produces a net force of 17,000N. The mass of the car (and occupants) is 1250kg. What is the acceleration of the car? Include units on your answer.Cool Down!! [aka review-part -> still part of warmup...kinda like that quiz 2 rilliggght?] 5. A 2 kg medicine ball is accidentally dropped from the 3"d floor of the College of Science & Math building. [oops] You know a guy and he told you id you that this building is approximately 68.88 feet tall. Being the math-wis that you are you didn't fo didn't forget that 3.28 feet = 1 meter]. a. What is the initial velocity of the medicine ball? b. What is the final velocity of the medicine ball? [Don't forget to be in SI units!] c. What time does the ball reach the surface
