A football is kicked with an initial velocity of 45 m/s at an angle of 30-degrees with the horizontal. Determine the time of flight, the horizontal displacement, and the peak height of the soccer ball. The tallest Ferris wheel in the world is located in Singapore. Standing 42 stories high and holding as many as 780 passengers, the Ferris wheel has a diameter of 150 meters and takes approximately 30 minutes to make a full circle. Determine the tangential velocity (in m/s) and the centripetal acceleration (in m/s2) of the riders on the Singapore Flyer.
The earth is spinning at 1 revolution per day. What is the magnitude of the coriolis acceleration on an object moving from the north pole at 10km/s?
As their booster rockets separate, Space Shuttle astronauts typically feel accelerations up to 3g, where g = 9.80 m/s2. In their training, astronauts ride in a device where they experience such an acceleration as a centripetal acceleration. Specifically, the astronaut is fastened securely at the end of a mechanical arm, which then turns at constant speed in a horizontal circle. Determine the rotation rate, in revolutions per second, required to give an astronaut a centripetal acceleration of 3.00g while in circular motion with radius 9.45 m.
For an object travelling with “uniform circular motion,” its acceleration is a. zero because the speed is constant b. directed tangent to the circle c. directed toward the centre of the circle d. changing in magnitude depending on its position in the circle e. directed outward from the centre of the circle
An airplane flies in a horizontal circle of radius 500 m at a speed of 150 m/s. If the plane were to fly in the same 1000 m circle at a speed of 300 m/s, by what factor would its centripetal acceleration change?
You are watching a TV news program when they switch to some scenes taken aboard the space shuttle which circles 500 miles above the Earth once every 95 minutes. To allow the audience to appreciate the distances involved, the announcer tells you that the radius of the Earth is about 4000 miles and the distance from the Earth to the Moon is about 250,000 miles. When an astronaut drops her pen it floats in front of her face. You immediately wonder how the acceleration of the dropped pen compares to the acceleration of a pen that you might drop here on the surface of the Earth.
