4-1 graphing uniformly accelerated motion equipment position-time graph pencil objective during this investigation you will • study the behavior of an object under the influence of gravity using data from a position-time graph. procedure 1. study graph i, the position-time graph for an arrow shot vertically into the air. recall that the slope of the curve at any point is equal to the instantaneous velocity at that time. 2. determine the instantaneous velocity of the arrow att = 1, 2, 3, and 4 seconds. to do this, construct the tangents to the curve at these times and determine the slopes of the tangents. record your data in the second column of table 4-1. 3. plat a velocity-time graph on graph ii using data from table 4-1. 4. the slope of a velocity-time graph is equal to the acceleration. using the same method that you used in step 2, determine the accelerations at t = 0, 1, 2, 3, and 4 seconds. enter the values in the third column of table 4-1. 5. plot an acceleration-time graph on graph iii. interpretation 1. describe the magnitude and direction of the change in velocity with time. 2. what is the significance of a negative velocity? 3. what does the shape of the curve in graph iii tell you about the acceleration of gravity? 4. what is the acceleration when v = 0 m/s? explain. chapter 4 minilab merrill publishing company 1990. 1986 users of physics: principles problems have the publisher's permission to reproduce this page.
Is there any opitions? if you have the periodic table, the noble gases are 8a family, the halogen are the 7a family, and the nonmetal are carbon, nitrogen, phosphorus, oxygen, sulfur, selenium, fluorine, chlorine, bromine, iodine and astatine.
Answer from: Quest
Shania is trying to determine the oldest geologic unit on this map and the reason to why is she unable to do so is that the units are all the same age.. when there is the same age, there will be no oldest geologic unit and that i cannot be credible.

How are momentum and impulse related? impulse is a whim to do something, while momentum keeps it going impulse is another name fore instantaneous momentum the impulse acting on and object is equal to the change of momentum it causes. the impulse that acts on and object is the momentum that results.
Consider a system to be two train cars traveling toward each other. what is the total momentum of the system before the train cars collide? kg • what must the total momentum of the system be after the train cars collide? kg •
