A 0.70 kg mass on a spring oscilates horizontally with a little friction acording to the
x= 0.0500 cos (2.10 t) where x is in meter and t is in seconds. Find the maximum energy stored in the spring during an oscilation. Find the maximum velocity of the mass.
V_max = w*A= (0.05)*(2.10)= 0.105 m/s
But the maximum energy E=(1/2)(m)(v_max ^2)= (1/2)(0.70)(0.105)^2= 3.86 x 10^-3 J
Is this problem correct?... or i use the wrong equations...
