The earth has a radius of 6380 km and turns around once on its axis in 24h.  a) What is the radial acceleration of an object on the ground at the earth’s equator? Give your answer in units of m/s and compare your result with the gravitational acceleration g. b) What is the radial acceleration of an object on the ground at the earth’s geographic North pole?

I understand to find the centripetal acceleration = v^2/r, but how do you figure that out when nothing is listed?

At the equator, the radius of the Earth is approximately 6370km. A jet flies at a very low altitude at a constant speed of v=222m/s Upon landing, the jet can produce an average deceleration of magnitude a=16.5m/s2 how long in seconds will it take the jet to circle the earth at the equator

2.) Which one of the following state at is true? Look at picture

In each of the four situations below an object is experiencing (nearly) uniform circular motion. State what force is providing the centripetal force required to keep the object moving in a circle: а. A car driving around a track. b. A ball being swung on the end of a string. С. The moon orbiting the earth. d. A rotating wheel.

An object is moving counterclockwise around a circular track at a constant speed of 3 m/s. The track is centered at the origin and has a radius of 1 m. What is the object's acceleration vector when it is at point P shown? y. P -(3플)i ○금3 + (3프) i a = +(9) i m Oa = 0 -(9플)i

In the movie Kill Bill the character Gogo Yubari fights with a meteor hammer, which is a bladed metal sphere on the end of a chain.  Let’s assume Gogo is spinning the meteor hammer in a vertical spin, as shown below, with a radius of motion as 1 m. She spins the weapon at 18 m/s.  Gogo then lets out more chain, increasing the radius to 1.62 m.  What is the new velocity of her weapon?

A hawk flies in a horizontal arc of radius 15.2 m at a constant speed of 5.4 m/s. Find its centripetal acceleration. Answer in units of m/s 2 .   It continues to fly along the same horizontal arc but increases its speed at the rate of 1.61 m/s 2. Find the magnitude of acceleration under these new conditions. Answer in units of m/s2

Jack goes for a ride on a ferris wheel that has a radius of 37 meters. The center of the ferris wheel is 49 meters above the ground. He starts his ride at the 12 o'clock position and travels counter clockwise. Define a function g that represents Jack's horizontal distance in meters relative to vertical midline of the wheel in terms of the angle (measured in radians) Jack makes with the center.

A race-car starts at the 3 o’clock position and drives counterclockwise on a circular track with a radius 4 miles. Suppose the car travels at a constant speed of 80 miles per hour. How long does it take the race-car to complete one revolution around the track? Include units.
