Problem 1 {Dynamics of Uniform Circular Motion}

The linear speed(Velocity) of a person riding a ferris wheel is 8.0m/s. What would be this person's linear speed if they were clinging to a spot halfway between the center of the wheel and the outer edge?

Problem 2 {A car rounding a curve}

A car with mass of 2565kg is rounding a horizontal curve of radius 76m. What is the maximum safe speed the car can maintain around the curve. Where m=0.73(dry road) and m=0.30(wet road)

Problem 3 {Gravitational Forces}

Calculate the gravitational force of:

-The sun and the earth

-The moon and the Earth

-Which is larger and how many times larger is it?

Earth: mass 5.97*10^24 kg

Radius 6,380,000 meters

Moon: mass 7.35 *10^22 kg

Radius 1,740,000 meters

Sun: mass 1.99*10^30

Radius 696,000,000

GOOD LUCK!
