What is the radius of a bobsled turn banked at 75.0^\circ75.0 ∘ and taken at 30.0 m/s, assuming it is ideally banked?
1 answer:
Banking angle is the angle between the normal horizontal path (N) and the curved banked path. The angle of banking of a curved path is defined as the angle through which the outer edge of the road is raised over the inner edge.
It is calculated as:
Here,
v = Linear velocity of object
r = Radius of the curved path
= Acceleration due to gravity
Rewriting the equation to solve for the radius we have that
Therefore the radius of a bobsled turn banked at 75° taken at 30m/s is 24.6m

Answer:
gravitational force
electrostatic force
Explanation:
The forces that balloons may exert on each other can be gravitational pull due to the mass of the balloon membrane and the mass of the gas contained in each. This force is inversely proportional to the square of the radial distance between their center of masses.
The Mutual force of gravitational pull that they exert on each other can be given as:
where:
gravitational constant
are the masses of individual balloons
the radial distance between the center of masses of the balloons.
But when there are charges on the balloons, the electrostatic force comes into act which is governed by Coulomb's law.
Given as:
where:
are the charges on the individual balloons
R = radial distance between the charges.
