PHYSICAL SCIENCE A 0.16-kilogram ball attached to a string is being spun in a circle 7.26 meters per second. The expression", where m is the mass of the ball, o is
the velocity, and r is the radius, can be used to find the force that keeps the ball
spinning in a circle. If the circle has a radius of 0.5 meter, find the force that must
be exerted to keep the ball spinning. Round to the nearest tenth.

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
