A simple pendulum completes 40 oscillations in one minute. Find its time period .

Two simple pendulum with heavy bobs-one using iron wire and the other aluminimum wire are excited simultaneously. It is found that when the first pendulum completes 1000 oscillations the other completes 1001. When the temperature is raised by t^(@)C , it is found that the two pendulums now oscillate together. If he coefficients of thermal expansion of iron and aluminimum are 10 xx 10^(-6)//^(@)C and 30 xx 10^(-6)//^(@)C then the value of t is :

You are riding an automobile of mass 3000kg. Assuming that you are examining the oscillation characteristics of its suspension system. The suspension sags 15cm when the entire automobile is placed on it. Also, the amplitude of oscillation decreases by 50% during one complete oscillation. Estimate the values of (a) the spring constant k and (b) damping constant b for the spring and shock absorber system of one wheel, assuming that each wheel supports 750kg.g=10m//s^(2) .
