Which one of the following graph for a body moving along a straight line is possible?
Evident that only option 4 is possible.
Option 1 is not possible as there can't be two speeds for the same time.
Same goes for option 3
Option 2 is a condition of variable jerk(da/dt = jerk) but is not possible as the graph goes under the x-axis (Speed can't be negative)
Option 4 is correct as it is a case of variable acceleration.
