Answer:
Step-by-step explanation:
In a velocity vs time graph, the slope of the graph is the acceleration. The area below the graph is the displacement. This gives the following answers:
19)
positive acceleration in A,B
negative acceleration in D,E
20)
greatest magnitude of acceleration in B
21) the object is standing still at the beginning of A
22) the speed is not changing in C
23) the area below the graph in A is 25/2 = 12.5
24) The area below the graph in B is 25 + 50/2 = 50
