I need help with these question from physics. I decided to take on an extra practice worksheet to study but I'm stuck. Please solve and explain the questions below. Everything is given in the attachments, thanks!!

SHM HWK Part 2 91.01 . You need to know the height of a tower, but darkness obscures the ceiling. You note that a pendulum extending from the ceiling almost touches the oor and that its period is 125. How tall is the tower? If the length of the pendulum in problem #1 were halved, what would its period of oscillation be? Atrapeze artist swings from the extreme right to the extreme left in 3.5 s, what is the length of their trapeze. Assume this happens on Earth (g=9.8 m/s"2) What is the frequency of a car's spring suspension system if the spring constant is 20,000 N/m and the mass is 3,000kg. Remember, find the period of oscillation first and then solve for frequency. How long will it take for the car in problem #4 to go through 3 oscillations? A spring with a spring constant of 180 Mm undergoes 9 oscillations in 5 seconds. a. What is the period of oscillation? b. What is the frequency of oscillation? c. What is the mass that is oscillating? A simple 2m long pendulum oscillates in a location where g=9.8 m/s"2. How many complete oscillations does this pendulum make in 5 minutes
