feet deep O 563452 cubic feet and 2390 9 cubic meters 33150 cubic feet and 938. 7 cubic meters O102150 cubic feet and 1887 3 cubic meters O 456231 cubic feet and 2127 5 cubic meters QUESTION 10 0 meters away from a hill throws a stone from the ground level at an angle of 60.0 above the horizontal with an initial speed of 25.0 m/s. The time It takes the stone to reach the hill and the O t-14s, y 18.6m height at which the stone strikes the hill are: O t-2.6s, y-11.5m ick Save and Sbemit to nd ubeit Cick Save All Aers to save all aners

Explanation / Answer

in horizontal, (a = 0 )

Dx = (v0x) t

20 = (25 cos60) t

t = 1.6 sec  

in vertical,

yf - yi = v0y t + ay t^2 /2

y =- 0 = (25 sin60)(1.6) + (-9.8 x 1.6^2 /2)

y = 22.1 m

Ans: t = 1.6 s, y = 22.1 m
