Answer:
the height of the porch is H=1.91 m
Step-by-step explanation:
neglecting friction and assuming that the porch is horizontal, then the horizontal speed is v₀= 4 m/s and it does not change , thus he hits the base at
t= L/v₀ , L= horizontal distance
then for vertical motion , since the vertical velocity vy is 0 , the initial height is H ( the height of the porche) and the final height hf is 0 , we have
hf = H + vy*t - 1/2*g*t²
0 = H + 0 -1/2*g*t²
H = 1/2*g*t² = 1/2*g*(L/v₀)²
replacing values with g= gravity = 9.8 m/s²
H = 1/2*g*(L/v₀)² = 1/2*9.8 m/s² *( 2.5 m/ 4 m/s)² = 1.91 m
therefore the height of the porch is H=1.91 m
Answer:
in about 8 2/3 years
Step-by-step explanation:
The population difference of 13000 people is being erased at the rate of 1500 people per year. It will be gone in ...
13000/1500 = 26/3 = 8 2/3 . . . . years
The population of Lakeside will be 45000 -8667 = 36333 at that time. Eastside's population will be the same.
Eastville and Lakeside will both have populations of 36,333 in 8 2/3 years.
Answer:
12
Step-by-step explanation:
6 / .5 (same as 1/2)
or 6 X 
Remember when we divide by a fraction we do the following
Keep it (the first number stays the same)
Change it (convert from a division problem to a multiplication problem)
Flip it (flip the fraction that we are dividing by over - this is called a reciprocal)
Answer:
b) 300in^2
Step-by-step explanation:
area of triangle = base x heigth / 2
10 . x 10 / 2 = 100/2 =50
surface area of one face is 50
there 4 sides so 50 x 4 = 200
and the bottom is length x width = 10 x 10 = 100
100 + 200 = 300
