YS 1111L Part C Analyzing Acceleration-Time Graph:s Accel Time (sec) 10 Figure 1-3: Motion Graph Showing Acceleration vs. Time Data Table for Part C-Analyzing Acceleration-Time Graphs X final Ax V average 0-2 sec 2-4 sec 4-6 sec 6-8 sec 8- 10 sec

Answer 1

Area under acceleration time graph gives change in velocity

for time interval 0 - 2 sec :

area = 0

so $\Delta$v = 0

for time interval 2-4 sec :

area = (4 - 2) (3) = 6

so $\Delta$v = 6 m/s

for time interval 4-6 sec :

area = (6 - 4) (3) = 6

so $\Delta$v = 6 m/s

for time interval 6-8 sec :

area = (8 - 6) (0) = 0

so $\Delta$v = 0 m/s

for time interval 8 - 10 sec :

area = (10 - 8) (- 6) = - 12

so $\Delta$v = - 12 m/s

for time interval 2-4 sec :

area = (4 - 2) (3) = 6

so $\Delta$v = 6 m/s
