We are given the equation:
s(t) = gt² + v₀t + s₀
g=-4.9, v₀ =19.6 and s₀=24.5
plugging these values in the equation we get,
s(t)=-4.9t² +19.6t +24.5
Non when it hits the ground final height s(t) will be 0
0=-4.9t² +19.6t +24.5
first option is correct
Y = 15 and X = 72°
Explanation = 72 + 108 = 180
D is equal to 47. You can plug it in and check it
