50 points, i need ! i need this experiment done with all results so i can get a good grade!
will brainliest if all work is shown

for this experiment, you will need a 12” ruler, some nickels and quarters, and a triangular shaped piece of wood to use as a fulcrum. we are going to ask the question: how does moving the fulcrum point effect the distance a nickel can fly? balance the ruler so there is an equal length on both sides of the fulcrum (at the 6” mark). put a nickel at the one inch mark on the ruler. record your observations in the data table. keep the nickel at the 1” mark. drop a quarter on the end of the opposite end of the ruler from about 12 inches in height. measure the distance from the end of the ruler to where the nickel lands. record your results. repeat this 3 times. now move your fulcrum to the 9 inch mark and repeat steps 2-4. now more your fulcrum to the 12 inch mark and repeat steps 2-4. which causes the
nickel to fly farther? which takes more force?

Aball is thrown upward. at a height of 10 meters above the ground, the ball has a potential energy of 50 joules (with the potential energy equal to zero at ground level) and is moving upward with a kinetic energy of 50 joules. what is the maximum height h reached by the ball? consider air friction to be negligible. 1. h ≈ 10 m 2. h ≈ 50 m 3. h ≈ 30 m 4. h ≈ 40 m 5. h ≈ 20 m 003 10.0 points which of the two object shown below has the greatest kinetic energy? a m b 1 2 m v 2v 1. kinetic energies are the same. 2. a 3. b 4. unable to determine. 004 10.0 points tim, with mass 74.6 kg, climbs a gymnasium rope a distance of 3.1 m. the acceleration of gravity is 9.8 m/s 2 . how much potential energy does tim gain? answer in units of j. 005 10.0 points a car is moving at 64 miles per hour. the kinetic energy of that car is 5 × 105 j. how much energy does the same car have when it moves at 111 miles per hour? answer in units of j. 006 10.0 points an 102 kg man climbs up a 1 m high flight of stairs. the acceleration of gravity is 9.81 m/s 2 . w

Suppose that a mass of 2 kg is attached a spring whose spring constant is 50. the system is damped such that b = 12 . the mass is set in motion with an initial velocity of -8 m/s at a position 0 meters from equilibrium. set up and solve a differential equation that models this motion. write your solution in the form a cos ( ω t − α ) where α is a positive number. use your solution to fill in the information below: what is the amplitude of the motion? what is the value of ω ? what is the phase shift?
