Speed v of a particle moving along a straight line, when it is at a distance x from a fixed point on the line
is given by v2 = 108 - 9x2 (all quantities in S.I. unit). Then

  • (A):The motion is uniformly accelerated along the straight line
  • (B):The magnitude of the acceleration at a distance 3 cm from the fixed point is 0.27 m/s2.
  • (C):The motion is simple harmonic about x = m.
  • (D):The maximum displacement from the fixed point is 4 cm.

Best Answer

Correct Answer:

(B): The magnitude of the acceleration at a distance 3 cm from the fixed point is 0.27 m/s2.
