An 73-kg bungee jumper is enjoying an afternoon of jumps. The jumper's first oscillation has an amplitude of 14 m and a period of 6 s. the spring constant of the bungee cord is 80.1 and max speed during oscillation is 14.7 m/s Treating the bungee cord as...

A clock has an aluminum pendulum with a period of 1.000 s at 20.3 °C. Suppose the clock is moved to a location where the average temperature is 28.1 °C. (The linear expansion coefficient for aluminum is 2.20 10-5 °C−1.) (a) Determine the new period of the...

One second after being thrown straight down an object is falling with a speed of 20m/s. How fast will it be falling 2 seconds later

then

how did you figure out distance from the center of mass?

if the mass is 9 kg instead of 8, would the L be 21.9

what equations do i use?

can you help more, i didn't get the right answer..i didn't get where you got 7.8 from

i didn't get the right answer

i get it wring when i enter it
