Question 1 15 pts In the first part of your activity you attempted reproducing the motion prescribed in the graph below (in purple). The figure also shows a recorded attempt (in red). Consider the part of the prescribed motion graph betwe ween the times t=0 and t=8 seconds. During how many seconds should a student stand still to r produce the prescribed motion? Question 2 15 pts In the first part of your activity you attempted reproducing the motion prescribed in the graph below (in purple). The figure also shows a recorded attempt (in red). Consider the part of the prescribed motion graph between the times t=0 and t=8 seconds. During how many seconds should a student move towards the sensor? Question 3 20 pts In the first part of your activity you attempted reproducing the motion prescribed in the graph below (in purple). The figure also shows a recorded attempt (in red). 00:08.00 Consider the part of the prescribed motion graph between the times 1=0 and t=8 seconds. What is the maximum speed (in m/'s) in the prescribed graph? Remember that speed the magnitude of the velocity. This is always a non-negative number. Question 4 15 pts In the second part of your activity you attempted reproducing the motion prescribed in the velocity graph below (in black). The figure also shows a recorded attempt (in red). Proposed vebay 'Tme refueloctyls)' Velocity graph Consider the part of the prescribed motion graph between the times =0 and t=8 seconds. The prescribed motion has segments where students should stay still. What is the total time that students should stay still according to the prescribed motion? Question 5 15 pts In the second part of your activity you attempted reproducing the motion prescribed in the velocity graph below (in black). The figure also shows a recorded attempt (in red). Proposed ve bery Velocity graph Consider the part of the prescribed motion graph between the times t=0 and t=8 seconds. The prescribed motion has segments where students should move away from the sensor and towards the sensor. At what time does the segment with motion towards the sensor begins? Question 6 20 pts In the second part of your activity you attempted reproducing the motion prescribed in the velocity graph below (in black). The figure also shows a recorded attempt (in red). 27 Velocity Proposed ve bcay Velocity graph Acceleration is the rate of change of the velocity of an object. The prescribed motion between time 1=7 sec to time t=7.5 sec has constant acceleration. Its value is the slope of the graph between these two times. Determine the acceleration of the prescribed motion during this period of time. Answer in m/s
