Answer:
6.46
Step-by-step explanation:
h(t) = (1/2) + v0t + h0
Origin is at surface of water (h = 0), up is positive.
a = -g = -9.8 m/
v0 = 25 m/s
h0 = 50 m
h(t) = -4.9t2 + 25t + 50
Find t when
7 = + 25t + 50
- 25t - 43 = 0
t = [1/(2*4.9)] [25 ±√( + 4*4.9*43)]
t = (0.102)(25 ± 38.312)
t > 0 ⇒ use only the positive square root
t = (0.102)(25 + 38.312) ≅ 6.46 s
It is 7m above the water at about 6.46 s
Answer:
1. 12 ft
2. 42.86 ft
Step-by-step explanation:
1. 5/24 = 2.5/<em>x</em>
<em> </em>5x<em> </em>=<em> </em>60
<em> x = </em>12 ft
2. 5/<em>x</em> = 7/60
7<em>x</em> = 300
x = 300/7 = 42.857 ft
So the ratio is 40/26 = 1.54
24 ÷ 1.54 = 15.58
2x-4 = 15.58
2x = 19.58
x = 9.8
