• Mathematics is not only about answer-getting. Students need to model situations and attend to meanings of quantities. Traditionally, multi -step word problems have focused almost entirely on the solution; however, standard 4.OA.A.3 has other key components to highlight. For example, question 3
• S = 10 mi/hr A car starts from a stoplight and is traveling with a velocity of 10 m/sec east in 20 seconds. What is the acceleration of the car? First we identify the information that we are given in the problem: vf - 10 m/sec vo - 0 m/sec time - 20 seconds Then we insert the given information into the acceleration formula:
• figure at right. The freshman’s horizontal velocity is 8 m/s. Assume gravity is 10 m/s per second. 2. (a.) ___ y = y o ½gt2___ What is the formula for height you would use for this problem (already “adjusted” for the problem situation)? Ans. The formulas for vertical motion that have time in them are y = y o ±v yo t ½gt2 and v yf = ±v ...
• 12 days of Alex and Sam is 10 tables, so: 12a + 12s = 10. 30 days of Alex alone is also 10 tables: 30a = 10. We are being asked how long it would take Sam to make 10 tables. Solve: 30a = 10, so Alex's rate (tables per day) is: a = 10/30 = 1/3
• find the value of the constant velocity at any instant between t = 0 and t = 40 s. Thus, the velocity at t = 25 s is . (b) We use a similar method to find the constant velocity between t = 40 s and t = 50 s: At t = 45 s, the velocity is .

Before learning about average speed and average velocity, we must know the difference between distance and displacement. Distance is a scalar quantity which generally implies how much ground has been covered by the object. a. Describe how you would prepare 1.0 L of a 0.10 M solution of sulfuric acid from a 3.0 M solution of sulfuric acid. Answer: Calculate the volume of 3.0 M sulfuric acid needed to prepare the dilution. M reagent × V reagent = M dilution × V dilution 3.0 M × V reagent = 0.10 M × 1.0 L V reagent = 0.033 L = 33 mL
