The speed $v$ of a particle moving along a straight line, when it is at a distance $x$ from a fixed point, is $v^{2} = 144 - 9 x^{2}$ (SI units):

Answer:

A, B, C, D

Solution:

$a = - 9 x$ : SHM with $ω = 3$ , $T = 2 π /3$ . $a (3) = 27$ . $A^{2} = 144/9 = 16$ , $A = 4$ . Displacement cannot exceed distance travelled.
