Answer:
A=28.13 Sq Ft
Step-by-step explanation:
Given that the length of the garden = 4.5 ft
Breadth of the garden = 6.25 ft
Area is given by the formula
A=length x breadth
A=4.5 x 6.25 sq ft
A= 28.125 sq ft
Here if we round the area to the nearest hundredth, the area will be
A=28.13 Sq Ft
Answer:
259.6 ft/sec
Step-by-step explanation:
it is a universal standard that acceleration due to gravity is 32ft/sec^2.
Now it can be verified by equation,
V(f) = V(i)+at (1st equation of motion derived by Newton's three laws of motion)
where,
V(f) is final velocity
V(i) is initial velocity
a is acceleration which is constant and have value 32ft/sec^2
t is time which is given as 7.8 seconds
In the given case, initial velocity that is V(i) will be 0ft/sec. Because, on dropping, object will start to move under the influence of gravity from zero speed.
So,
V(f) = 0 +(32) (7.8)
V(f) = 249.6 ft/sec
Now the condition is given that you have to add a constant 10 to the answer.
so, V(f) = 249.6 + 10
V(f) = 259.6 ft/sec
