A particle moves along a straight line to follow the equation ax2+bv2 = k, where a, b and k are constants and x and v are x-coordinate and velocity of the particle respectively. Find the amplitude.

a
kb
b
bk
c
ak
d
ka

detailed solution

Correct option is D

ax2+bv2 = k             bv2 = k-ax2            v2 = kb-abx2Compare with v2 = A2ω2-ω2x2ω2 = ab  and A2ω2 = kbA = A2ω2ω2 = kbab = ka
