A granite block starts sliding on a slope (inclination of 30° with the horizontal) under the effect of gravity only, along the true direction of inclination of the slope and hits the ground in 4 seconds. Considering zero friction and zero cohesion during sliding, the vertical height of the point (with respect to the ground) from where the block was dislodged is _____m. (g = 10 m/s2) (In integer)
An ore body defined by a 300m x 300m area is shown in the figure in which the drill hole locations on equally spaced square grid are marked (numbers 1-16). The average thickness of the ore body at the 4 interior points is 10.8m, at the 4 corners is 11.0m and at the remaining 8 boundary locations is 10.5m, respectively. The corresponding average grades are 1.5, 1.9 and 1.8wt%, respectively. Calculate the average grade (in wt%) of the full ore body using the Included Area Method. (Round off to two decimal places).
