The displacement-time graph of a particle is a triangle: displacement rises linearly to a peak and then falls linearly back to zero. This graph:
Options:
Answer:
B
Solution:
Displacement can decrease (the particle comes back), so the shape is allowed in principle; but the velocity (slope) jumps from one finite value to another at the corner, which needs an infinite acceleration. A real graph would be smooth at the top. Option B.
