According to this graph, the velocity is approximately:
A) 3.0 m/s
B) 4.5 m/s
C) 5.0 m/s
D) 4.0 m/s
​

Answer 1

A. 3.0 m/s

Explanation:

Based on the graph,

velocity = Area of the graph

(y : position and x : time)

Let y1 = 2m and y2 = 14m,

t1 = 0s and t2 = 4s

v = (14 - 2)m/(4-0)s

= 12m/4s

= 3.0 m/s

Answer 2

A. 3.0 m/s

Explanation:

Based on the graph,

velocity = Area of the graph

`v = (y1 - y2)/(x1 - x2)`

(y : position and x : time)

Let y1 = 2m and y2 = 14m,

t1 = 0s and t2 = 4s

v = (14 - 2)m/(4-0)s

= 12m/4s

= 3.0 m/s
