Answer:
It traveled 24 centimeters
Explanation:
The displacement of the object is equal to the area under the velocity vs time graph.
We can split this graph into two shapes, a triangle and a rectangle. So the total area is:
A = ½bh + wh
A = ½ (4 s − 0 s) (4 cm/s) + (8 s − 4 s) (4 cm/s)
A = 8 cm + 16 cm
A = 24 cm
Answer:
10 m^3 /s
Explanation:
1 m X 2 m X 5 m /s = 10 m^3/s
