Ablock with mass m =7 kg is hung from a vertical spring. when the mass hangs in equilibrium, the spring stretches x = 0.29 m. while at this equilibrium position, the mass is then given an initial push downward at v = 4.1 m/s. the block oscillates on the spring without friction.

1) what is the spring constant of the spring?
2) what is the oscillation frequency?
3) after t = 0.39 s what is the speed of the block?
4) what is the magnitude of the maximum acceleration of the block?
5) at t = 0.39 s what is the magnitude of the net force on the block?

because it says use -2,0,and 2 for x, we can plug those numbers into the equation. y/4=3/4(-2)+2   y/4= -1 1/2 +2 now to get x by itself, we can multiply each side by 4. y=-6+8 which equals y=2 when x=-2. now you can do the same thing with 0 and 2 as x. you get y=8 when x=0 and y=14 when x=2.

x   |   y

-2 |   2

0   |   8

2   |   14

"i have always loved contemporary art and made it a general goal to work within the field. after a few nonprofit internships at museums and galleries, i decided to try the for-profit art world and was offered a job as the ad assistant at the magazine. i much prefer the pace of the for-profit art community and have stayed with the company for three years, with a promotion to an account manager last spring."

i just did this and got a 100.
