Answer:
a)Tt = 21,41 s
b) y(max) = 1873 ft
c) t = 10,70 s
Step-by-step explanation:
We assume that this is a case of vertical shooting then:
a) Vf = V₀ - g*t
Vf = 0 -g*t = -V₀
t = V₀ /g t = 350 ft/s / 32,7 ft/s²
t = 10,70 s time for lava to reach y maximum
a) Then Tt = 2*10,7 Tt = 21,41 s
Lava was in the air for Tt = 21,41 s
b) y = y₀ + v₀*t - (1/2 )*g*t²
for y = ymax we get:
y(max) = 0 + 350*10,70 - 0,5* 32,7* ( 10,70)²
y(max) = 3745 - 1872
y(max) = 1873 ft
c) t = 10,70 s
C I hope that help I had that
Answer:
805
Step-by-step explanation:
x=y-120÷7
y÷7=y-720÷7
7y=y-4830
y=4830÷6
y=805
Answer:
42 hours
Step-by-step explanation:
1 pound = 3,500
3,500 × 3 = 10,500
1 hour = 250
10,500 ÷ 250 = 42
42 hours
Answer:
2, -3
Step-by-step explanation:
4 units down is -9, then a reflection over y axis makes -2 2 6 units up makes -9 -3
