Graphs I and II give coordinates x(t) and y(t) of a particle moving in the x-y plane, starting from rest. Acceleration of the particle is constant and the graphs are drawn to the same scale. Which of the vector shown in options best represents the acceleration of the particle:
(I) 
(II) 
A
B
C
D
Answer
Explanation
Solution
By combining x and y coordinate, motion of the particle is shown in xy plane. As the particle has started from rest, acceleration must be along this direction.
