V. Finding displacement using V vs t graphs
Area under the plot
= displacement (distance)
Ex) What is the displacement this object covered from t = 0 to t = 6 seconds?
d = Area of the triangle:
= 1/2bh
= 1/2(6 sec)(70m/sec)
= 210 m
Ex 1)
 |
Object's displacement from
t = 1 sec to t = 3 sec?
 |
d = Area = base x height
= (2 sec)(10 m/sec) = 20 m
Ex 2) Object's displacement
from t = 6
sec to t = 8 sec ?
d = area of trapezoid
= 1/2 (h1 + h2) x base
| d = | (25 m/s + 10 m/s) | (2 sec) | |
| 2 | |||
= 35 m
