When the rock is suspended from a string and totally immersed in a liquid, the tension in the string is 6. 0 n. T,on: calculate the force that the liquid exerts on the rock, calculate the density of the liquid. A small rock is projected from ground level with an initial velocity that has magnitude vc, = 40 rn/s and that is at an angle of 53 above the horizontal. The rock strikes the vertical wall of a building 4. 0 s after it leaves the ground. C: calculate the horizontal distance from the initial position of the rock to the wall of the building. Ans: calculate is the vertical height above the ground of the point where the rock strikes the building. A 20 kg block is placed on a ramp that is inclined at 37 above the horizontal.
