Answer:
There are actually three, Kepler's laws that is, of planetary motion: 1) every planet's orbit is an ellipse with the Sun at a focus; 2) a line joining the Sun and a planet sweeps out equal areas in equal times; and 3) the square of a planet's orbital period is proportional to the cube of the semi-major axis of its

Answer:
-969.06
-286.74
698.7
-115.6, 12.9
-139.9, 12.9
Explanation:
Given that
Speed v, wrt y = -24.3 m/s
Speed v, wrt x = 12.9 m/s
time t, = 11.8 s
a
Using the formula
H(t) = ut - 1/2gt², where u = v wrt y
H(t) = -24.3 * 11.8 - 1/2 * 9.8 * 11.8²
H(t) = -286.74 - 682.28
H(t) = -969.06 m
b
H = ut, where u = v wrt y
H = -24.3 * 11.8
H = -286.74 m
H(1) = -969.06 - -286.74 = -682 m
c
Horizontal displacement, x = vt. Where v = v wrt x
x = 12.9 * 11.8
x = 152.22 m
d = √(H1² + x²)
d = √682² + 152²
d = 465124 + 23104
d = √488228
d = 698.7 m
d
Vertical component =
-gt - 0 =
-9.8 * 11.8 = -115.6
Horizontal component =
v wrt x - 0
12.9 - 0 = 12.9
e
Vertical component =
-gt - v wrt y =
-9.8 * 11.8 - 24.3 = -139.9
Horizontal component =
v wrt x - 0 =
12.9 - 0 = 0
