12. A lump of ice (density 920kg/m”) is put into a tumbler containing a coke. The density of<br />coke is 1150kg/m? What fraction of the lump of ice will be above the surface of the<br />coke?​

Aparticle moves in the xy plane with constant acceleration. at time zero, the particle is at x = 6 m, y = 8.5 m, and has velocity ~vo = (9 m/s) ˆı + (−2.5 m/s) ˆ . the acceleration is given by ~a = (4.5 m/s 2 ) ˆı + (3 m/s 2 ) ˆ . what is the x component of velocity after 3.5 s? answer in units of m/s.
