Answer:
l = 44 ft
w = 20 ft
Step-by-step explanation:
Perimeter is
P = 2 ( l+w)
The width is
w = l -24
We know the perimeter is 128 and substituting into the equation for perimeter
128 = 2 ( l + l-24)
128 = 2 ( 2l -24)
Divide by 2
128/2 = 2/2 ( 2l-24)
64 = 2l - 24
Add 24 t o each sdie
64+24 = 2l
88 = 2l
Divide by 2
44 =l
The length is 44
Now find w
w = l - 24
w = 44-24
w = 20

Answer:
187 ft/s
Step-by-step explanation:
Given in the y direction:
v₀ = 0 ft/s
Δy = 75 ft
a = 32 ft/s²
Find: t
Δy = v₀ t + ½ at²
(75 ft) = (0 ft/s) t + ½ (32 ft/s²) t²
t = 2.165 s
Given in the x direction:
Δx = 480 ft
a = 0 ft/s²
t = 2.165 s
Find: v₀
Δx = v₀ t + ½ at²
(480 ft) = v₀ (2.165 s) + ½ (32 ft/s²) (2.165 s)²
v₀ = 187 ft/s
