Answer:
<u>Initial</u><u> </u><u>speed</u><u> </u><u>is</u><u> </u><u>3</u><u>2</u><u> </u><u>m</u><u>/</u><u>s</u>
At uniform speed, acceleration is 0, (a = 0).
When speed reduced, (v - u) = 2.78 ms-¹, t = 1800 sec, s = 60 ,000 metres.
From first equation of motion:

substitute:

from second equation of motion:

substitute:

18 + 2y + 6 = 36
2y = 12
y = 6
Since RS bisects AB,
25 - 3x = 2y + 5
25 - 3x = 2(6) + 5 = 12 + 5 = 17
3x = 25 - 17 = 8
x = 8/3
Answer:
y=5.5x+100
Step-by-step explanation:
since the $5.50 is your variable, you set that to the x value, and 100 to reserve is your y intercept because it is constant.
