Your car's wheels are 65.0 cm in diameter, and the wheels are spinning at an angular velocity of 140 rad/s. How fast is your car moving assume no slippage)? km/h PhotoGrid A car approaches the top of a hill that is shaped like a vertical circle with go over the hill without losing contact with the ground ? the fastest speed that the car can Required information m/s A small object of mass 0.500 kg is attached by a 0.810 m-long cord to a pin set into the surface of a frictionless table top. The object moves in a circle on the horizontal surface with a speed of 5.97 m/s. What is the magnitude of the radial acceleration of the object? m/s Check my work Required information blink of an eye" is a time interval of about 150 ms for an average adult. The "closure" portion of the blink takes only Required information about 55 ms. Let us model the closure of the upper eyelid as uniform angular acceleration through an angular A small object of mass 0.500 kg is attached by a 0.810 m-long cord to a pin set into the surface of a frictionless table top. The object moves in a circle on the horizontal surface with a speed of 5.97 m/s. What is the value of the angular acceleration the eyelid undergoes while closing? What is the tension in the cord? rad/s N ! Required information Required information about'sgoran eye" is a time interval of about 150 ms for an average adult. The "closure" portion of the blink takes only A curve in a stretch of highway has radius 518 m. The road is unbanked. The coefficient of static friction between the tires displacement of 14.5 What is the tangential acceleration of the edge of the eyelid while closing if the radius of the eyeball is 1.25 cm? What is the maximum safe speed that a car can travel around the curve without skidding? m/s m/s 2 Required information The ability of the human eye to rapidly rotate was studied using contact lenses fitted with acce whose eyeball has radius 1.25 cm, watches a moving object her eyeball rotates through 20.0 in a time interval of 75.4 ms . A roller coaster has a vertical loop with radius 17.9 m. With what minimum speed should the roller-coaster car be moving at the top of the loop so that the passengers do not lose contact with the seats? Im/s What is the magnitude of the average angular velocity of the eye? rad/s
