Question
Hello, Ive attached the pics of the activity and i have answered them but i want someone who can show the steps for the qestions thats need to be solved step by step. I got the answers for 1- (0,2) 2- (4,5) 3- (2,4) but for some questions like 5 and 6 need calculation and explaintion. Can someone confirm my answers and help with the rest ..
OBJECTIVE To find out how to record motion with a motion detector To find out how motion looks as a distance (position)-time graph To find out the connection between velocity and actual motion To find out how the motion looks in a velocity-time graph To understand meaning of acceleration, its magnitude and direction To find out the relationship between distance, velocity and acceleration graphs EQUIPMENT NEEDED Available at each table: Motion detector Laboratory Interface Computer Dynamics car Dynamics Track PRE-LAB ACTIVITY The Pasco motion sensors use ultrasonic sound waves to measure your position. As you move away from the sensor, your distance increases.Use the following graph to answer questions 1-3. 1. During what time interval are you moving away from the sensor? During what time interval are you moving towards the sensor? During what time interval are you not moving? Use this graph to answer questions 4 5, and 6. 4. Which person is moving faster? A or B? Calculate the slopes for both persons. What does the slope of a distance vs time graph represent? Use this graph to answer questions 7-11. 7. During what time interval are you moving away from the sensor? During what time interval are you moving towards the sensor? During what time interval are you not moving (stationary)? When are you moving faster? At 1 second or at 3 seconds? When are you moving faster? At 9 seconds or at 11 seconds?
Explanation / Answer
4. A is moving faster. (Slope is greater)
5. A: 0.8 m/sec (4/5)
B: 0.4 m/sec(2/5)
6. It gives us speed of the object.
7. 0-6 Seconds.(Velocity is positive)
8. 8-14 seconds(Velocity is negative)
9. 6-8 seconds.(VeloCIty is zero)
10. 3 Seconds()
11. 11 seconds
