In Trial II, the same spring is used as in Trial I. Let us use this information to find the suspended mass in Trial II. Use 0.517 ss for the value of the period.

Trial 1 Spring constant is 117N/m, period of oscillations .37s, mass of the block is .400kg .
Trial 2 oscillation period is .52s

Answer:


M_2=0.79kg

Step-by-step explanation:

From the question we are told that:

Period
T=0.517s

Trial 1

Spring constant
\mu=117N/m

Period
T_1=0.37

Mass
m=0.400kg

Trial 2

Period
T_2=0.52

Generally the equation for Spring Constant is mathematically given by

\mu=\frac{4 \pi^2 M}{T^2}

Since


\mu _1=\mu_2

Therefore


(4 \pi^2 M_1)/(T_1^2)=(4 \pi^2 M_2)/(T_2^2)


M_2=M_1*((T_2)/(T_1))^2


M_2=0.400*((0.52)/(0.37)})^2


M_2=0.79kg
