For centripetal acceleration, why not use ac = r * W2?
Helicopter blades withstand tremendous stresses. In addition to supporting the weight of a helicopter, they are spun at rapid rates and experience large centripetal accelerations, especially at the tip. (For each answer, enter a number.) (a) Calculate the magnitude (in m/s?) of the centripetal acceleration at the tip of a 3.00 m long helicopter blade that rotates at 240 rev/min. m/s? (b) Compare the linear speed of the tip with the speed of sound (taken to be 340 m/s). Vtip/V sound
A jet fighter flying at 300 m/s (just below the speed of sound) makes a turn of radius 2.55 km. (a) What is its centripetal acceleration in gs? (b) Suppose the pilot makes an emergency turn to avoid an approaching missile, subjecting himself to a centripetal acceleration of 10 gs, while flying at 565 m/s (supersonic). What is the radius, in km, of his turn? (This must be short-lived because fighter planes can only briefly endure such large accelerations without serious damage, and the pilot will soon black out at 10 gs.)
A child whirls a stone on a string in a horizontal circle of radius 1.5 m and at a height of 2.0 m above level ground. The string breaks and the stone flies off horizontally and hits the ground 13.3 m away horizontally. Determine the magnitude of the centripetal acceleration of the stone just before the string broke. (Use g = 10 N/kg).
What is the minimum radius at which an airplane flying at 143.6 m/s can make a U-turn if its centripetal acceleration is NOT to exceed 2.3 m/s??
An object in a circular orbit is moving at a constant speed. This is called centripetal acceleration. Yet the speed is constant. How is it accelerating?
