1. At an outdoor market, a bunch of bananas attached to the bottom of a vertical spring of force constant 16.0 N/m is set into oscillatory motion with an amplitude of 20.0 cm. It is observed that the maximum speed of the bunch of bananas is 40.2 cm/s. What is the weight of the bananas in newtons?
2. A spring hangs vertically from a fixed support. A mass is then attached to the lower end of a spring. When this system undergoes simple harmonic motion, it has a period of 0.67 s. By how much is the spring stretched from its initial length when the mass and spring are hanging motionless?
3. pendulum with a length of precisely 1.000 m can be used to measure the acceleration due to gravity, g. Such a device is called a gravimeter.
(a) How long do 145 oscillations take at sea level, where
g = 9.81 m/s2?
(Give your answer to at least two decimal places.)

(b) Suppose you take a gravimeter to the top of a high mountain, where the value of g is 0.25% less than the value at sea level. How long do 145 oscillations take at the top of Mount Everest? (Give your answer to at least two decimal places.)

Quick 3 questions, should only take u about 5-10 mins to do all if you know what you are doing..
I need this done withint next 2-3 hours, i will pay 65 fg for all. I think there are on google, with different numbers, but I need correct answers.
It seems I can't do it.. Thank you
