The graph to the right is a plot of position versus time. For which labeled region is the velocity positive and the acceleration negative?

Which graph represents positive acceleration ?

Which graph represents positive acceleration ?

A particle is moving along x-direction with a constant acceleration a. The particle starts from x=x_0 position with initial velocity u. We can define the position of the particle with time by the relation x=x_0+ut+(1)/(2)at^2 plot the position of the particle in relation with time is following situations (i) If initial position of the particle is on negativ x-axis, initial velocity is positive and acceleration is negative. (ii) If initial position is positive, initial velocity is negative and acceleration is positive.
