A10kg is dropped straight down on the floor and breaks into three pieces. the pieces then slide with friction (µk = 0.35) across the floor and come to rest away from the drop site. if the drop site is (x, y) = (0, 0), a 3kg piece is found at (x, y) = (1, −4), and a 4.5kg piece is found at (x, y) = (3, 0.5), where will the third piece be found?

Aplane flies directly between two cities, a and b, which are separated by . from a to b, the plane flies into a headwind. on the return trip from b to a, the wind velocity is unchanged. the trip from b to a takes less than the trip from a to b. what is the airspeed of the plane, assuming it is the same in both directions

Iwill give brainliest if you answer right : )

The pressure increases by 1.0 x 104 n/m^2 for every meter of depth beneath the surface of the ocean. at what depth does the volume of a pyrex (bulk modulus 2.6 x 1010n/m^2) glass cube, 9.8 x 10^−2m on an edge at the ocean's surface, decrease by 7.5 x 10−10m^3? explain the formula beyond this point: p=1.0x10^4, b=2.6x10^10, l=9.8x10^−2, delta v=7.5x10^−10. at some point l needs to be cubed. why p is divided by delta v?
