A)
OA, AB, BC, CD + 0 + +
B)
OA, AB, BC, CD - 0 + 0
C)
OA, AB, BC, CD + 0 - +
D)
OA, AB, BC, CD - 0 - 0
Correct Answer: B
Solution :
Region OA shows that graph bending toward time axis i.e. acceleration is negative. Region AB shows that graph is parallel to time axis i.e. velocity is zero. Hence acceleration is zero. Region BC shows that graph is bending towards displacement axis i.e. acceleration is positive. Region CD shows that graph having constant slope i.e. velocity is constant. Hence acceleration is zero.
