Answer
It increases to B, then it decreases.
When the stone thrown upwards, it moves vertically upwards to a maximum height then is starts to come down. Due to gravitational force, the velocity of the stone projected upwards decreases but when coming down wards is increases.
The trajectory shown in the diagrams represents an example of an object projected upwards.
We can then says that the vertical component increases from A to B, then it decreases to C.
Answer:
a) 0.069 acres
b) 0.114acres
c) 17.78acres
Explanation:
1 dot=1/36sqin
a) 1 sqin= 330×330=108900ft^2
1 dot=108900/36 =3025ft^2
Converting to acre,divide by43560
3025/43560 =0.069acre
b) 1 chain =22 yards
25×22=550yards
Converting to acre divide by 4840
550/4840 =0.114acre
c)1 sqmile =640acres
(1/36) ÷ 640
640/36
17.78acres
B is the correct answer according to my calculations.
