Equations of SHM
  1. A particle is subjected to two SHMs x1 = A1sin wt and x2 = A2 sin (wt + 180/4). The resultant SHM will have an amplitude of treat w as omega Answer is( A12 +A22+ (2)1/2A1 A2) 1/2 how
  2. A particle moves according to the law x=a cos pi.t/2. The distance covered by it in the time interval between t =0 to t=3 sec is 1)2a 2)3a 3)4a 4)a which is correct answers please.

x=Asinωt          (i)
y=Asin(2ωt+π/2)
   =Acos2ωt
   =A(12sin2ωt)
From Eq. (i)
sinωt=Ax
   y=A(1A22x2)
 
Thanks and regards
