Answer:
a. 
b. 
Explanation:
The data given are
Height,h=550ft,
length of incline plane, L=1.50 miles
first we convert all parameters to meters
since 1ft=0.3048m then 550ft will be 167.76m
also 1mile=1609.34m, hence 1.5mile will be 2414m
From the diagram attached, the length and height formed a simple triangle with the length being the hypotenuse and the height being the opposite.
Hence using SOHCAHTOA, we can conclude that the angle will be

b. the new height becomes

going by the same formula, we solve the new length s

Answer:
0.6944 m/sec^2
Explanation:
The computation of the average acceleration is given below:
a = v - u ÷ t
where
a denotes average acceleration
v denotes final velocity
u denotes initial velocity
t denotes time
So, the average acceleration is
= (25 - 0) ÷ 10
= 0.6944 m/sec^2
The answer of this question is B. 22x + 20
