Answer:
m= 1.47 kg
Explanation:
Given:
spring constant, K = 23.15 N/m
Displacement, x= 19.79 cm = 0.1979 m
at, x₁= 7.417 cm, v₁= 0.7286 m/s
Now,
x = 19.79 cos ( ωt)
on substituting the values, we get
7.417 x 10⁻² = 19.79 x 10⁻² cos (ωt)
or
cos(ωt) = 0.374
or
ωt = 67.98°
also
v = -0.1979×ωsin (ωt)
also
on substituting the values in the above equation, we get
0.7286 = -0.1979 sin ( 67.98°)
3.68 =-(0.927)
or
T = 1.582 sec
also,
where, m is the mass
on substituting the values, we have
on squaring both sides and solving, we have
m= 1.47 kg
