- A ferris wheel completes 2 revolutions in 60 seconds. Determine how far it has travelled in 15 seconds. the radius of the ferris wheel is 10 m.The acceleration due to gravity, g, is constant at sea level on the Earth's surface. However, the acceleration decreases as an object moves away from the Earth's surface due to the increase in distance from the center of the Earth. Derive an expression for the acceleration due to gravity at a distance h above the surface of the Earth, gh. Express the equation in terms of the radius R of the Earth, g, and h. 8h = Suppose a 70.00 kg hiker has ascended to a height of 1815 m above sea level in the process of climbing Mt. Washington. By what percent has the hiker's weight changed from its value at sea level as a result of climbing to this elevation? Use g = 9.807 m/s² and R = 6.371 × 106 m. Enter your answer as a positive value. weight change = %A circular track has a radius of 125 m. (a) Calculate the distance around the track.

- Consider a track in the shape of a perfect circle of radius 1 kilometer. A biker rides counter-clockwise at a constant speed around the track completing 3 laps every hour. Write a formula for the position of the biker (x(t), y(t)) t minutes after starting, where the origin is at the center of the track and the biker's starting position is on the posi- tive x-axis. Use this formula to compute how far the biker travels in their first 200 minutes of biking.With the height of 5.5 feet express it in English system and SI system.The acceleration due to gravity, g, is constant at sea level on the Earth's surface. However, the acceleration decreases as an object moves away from the Earth's surface due to the increase in distance from the center of the Earth. Derive an expression for the acceleration due to gravity at a distance h above the surface of the Earth, gh. Express the equation in terms of the radius R of the Earth, 8, and h.
