The net force on a particle moving in a straight line grows linearly from zero to a peak in 2 s and then falls linearly back to zero in the next 2 s, always along the velocity. Its speed-time graph over these 4 s is:
Options:
Answer:
B
Solution:
The slope of the - graph follows the force: it increases till 2 s and decreases after, leaving the curve steepest at 2 s and flat at 4 s (speed stays at its final value). Option B.
