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=

................ii

form i and ii we can write

v^2= \frac{1}{2} u^2v

⇒u= √2 v

therefore, safe speed for the larger radius track u= √2 v

Helga [31]

Answer:

Volume of a right prism = 65 cubic inches

Its height is increased by a factor of 20.

To find:

The new volume of the prism if the other dimensions do not change.

Solution:

The volume of a prism is:

$Volume=Bh$

Where, B is the base area and h is the height.

A right prism has a volume of 65 cubic inches.

$65=Bh$

The height of prism is increased by a factor of 20. So, the new volume is:

$Volume=B(20h)$

$Volume=20(Bh)$

$Volume=20(65)$

$Volume=1300$

The volume of the new prism is 1300 in³.

Therefore, the correct option is B.
