The answer is x=3 i believe
Answer:
Answer:
safe speed for the larger radius track u= √2 v
Explanation:
The sum of the forces on either side is the same, the only difference is the radius of curvature and speed.
Also given that r_1= smaller radius
r_2= larger radius curve
r_2= 2r_1..............i
let u be the speed of larger radius curve
now, \sum F = \frac{mv^2}{r_1} =\frac{mu^2}{r_2}∑F=
r

mv

=
r

mu

................ii
form i and ii we can write
v^2= \frac{1}{2} u^2v

=

u

⇒u= √2 v
therefore, safe speed for the larger radius track u= √2 v
2.8 or if rounded to the nearest tenth so 2.8√8
Answer:
Box A's volume is bigger by 864 cubic inches
Step-by-step explanation:
12 × 18 × 24 = 5184
12 × 12 × 30 = 4320
Then we subtract. 5184 - 4320 = 864
Answer:
x=9
Step-by-step explanation:
subtract 9 from both sides.
-3x = -27
divide by -3
x=9
