Area= pi x r^2 r=50/2
=pi x 25^2
=1963.5 inches
H(t) = 47t - 0.83t^2
Vo = 47m/s
V (t) = 47 - 1.66 t
a) t = 8 s; V(8) = 47 - 1.66(8) = 33.72 m/s
b) t = a; V(a) = 47 -1.66(a)
c) Hit the moon t =?
h(t) = 0 => 47t - 0.83 t^2 = 0
Factor: t (47 - 0.83t) = 0
47 - 0.83t = 0 => 0.83t = 47
t = 47 / 0.83 = 56.63 s
d) Velocity when hit the moon
The velocity of the arrow when it hits the moon is the same initial speed with opposite sign.
V = - 47 m/s
D(-1,-1), E(-8,-4), F(-8,-8)
Well, there was a two dollar decrease? Are you asking for the percentage or just what was decreased from the original price?
