For which of the following position-time (x-t) graphs is acceleration zero?
ScanSolve AI Answer
Step-by-step solution
5 stepsAcceleration is zero when velocity is constant.
In an - graph, constant velocity appears as a straight line (non-zero slope).
Observe the graphs: Graph (A) is a straight line (constant slope), so acceleration is zero throughout.
Graphs (B), (C), (D) are curved or piecewise, indicating changing velocity.
Answer for Q12: (A)
Maximum velocity from - graph is the highest value (peak ordinate).
Maximum displacement is the maximum area under - curve up to that point ().
Maximum acceleration is the maximum slope of - graph ().
Average displacement is total area under curve divided by time interval ().
(Specific values require graph scales; read from given - graphs for A, B, C, D.)
The area under - graph represents displacement (), not velocity or acceleration.
Velocity = ordinate value. Acceleration = slope.
neither (A) nor (B); it is displacement
