7% is the same as 7/100 so take
149.99 x 7/100 = $10.50 which is the TAX
and then add that to the original price
10.50 + 149.99 = 160.49
Kinetic engery = -1/2mv^2
Work = Fd
Combine:
-1/2mv^2 - Fd = 0
-1/2mv^2 = (0.30*15000*9.81*cos(6))d = 0
Multiply both sides by 2:
v^2 = 2d(0.30*9.81*cos(6))
Solve for d:
d=v^2 / 2(0.30*9.81*cos96))
v = speed:
d = 35^2 / 2*0.30 * 9.81 * cos(6)
d = 1225 / 5.85376
d = 209.27 meters. Round answer as needed.
Do you have step one? maybe i can try it but im not that good in math
Answer: x= 12/5 or 2 2/5
