One of the limiting factors in high-performance aircraft is the acceleration to which the pilot can be subjected without blacking out; it’s measured in “gees,” or multiples of the gravitational acceleration. The F-22 Raptor fighter can achieve Mach 1.8 (1.8 times the speed of sound, which is about 340 m/s). Suppose a pilot dives in a circle and pulls up. If the pilot can’t exceed 6g, what’s the tightest circle (smallest radius) in which the plane can turn?

- How fast would a car have to round a turn with a radius of 70 m for its acceleration to be numerically equal to that of gravity? Answer should be in terms of velocity, in m/s.arrow_forwardUniform circular motion is an example of accelerated motion because; a. the acceleration is constant. b. the acceleration is directed inward. c. the velocity is constantly changing in direction. d. the speed is constant.arrow_forwardFind the magnitude of the instantaneous acceleration (in m/s2) of an object that moves at a constant speed around a circle if it takes 7.01 s to complete one revolution. The radius of the circle is 1.62 marrow_forward

At an instant when the magnitude of the total acceleration is atotal, what is the speed of the particle? atotal=6.5 m/s2 r=4.0 marrow_forwardAs 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.arrow_forward
- In a classic clip on Americas Funniest Home Videos, a sleeping cat rolls gently off the top of a warm TV set. Ignoring air resistance, calculate the position and velocity of the cat after (a) 0.100 s, (b) 0.200 s, and (c) 0.300 s.arrow_forwardAs a raindrop falls through the atmosphere, its speed initially changes as it falls toward the Earth. Before the raindrop reaches its terminal speed, does the magnitude of its acceleration (a) increase, (b) decrease, (c) stay constant at zero, (d) stay constant at 9.80 m/s2, or (e) stay constant at some other value?arrow_forwardA rubber stopper on the end of a string is swung steadily in a horizontal circle. In one trial, it moves at speed v in a circle of radius r. In a second trial, it moves at a higher speed 3v in a circle of radius 3r. In this second trial, is its acceleration (a) the same as in the first trial, (b) three times larger, (c) one-third as large, (d) nine times larger, or (e) one-ninth as large?arrow_forward

Centripetal Forcearrow_forward1. An object is moving in a circular path at constant speed. If the speed is doubled then: a) The acceleration increases by four times. b) The acceleration is doubled. c) The acceleration is halved. d) None of the above. 2. An object is moving in a circular path at constant speed. If the radius of the circular path is doubled and the speed stays the same, then: a) The acceleration decreases by four times. b) The acceleration stays the same. c) The acceleration is halved. d) None of the above. 3. A 10 kg object is moving in uniform circular motion with a radius of 20 m. It takes the object 8 s to make one complete revolution. A. Find the speed of the object. B. Find the net force acting on the object.arrow_forwardHumans lose consciousness if exposedto prolonged accelerations of more than about 7g. This is of concern to jet fighter pilots, who may experience centripetal accelerations of this magnitude when making high-speed turns. Suppose we would like to decrease the centripetal acceleration of a jet.Rank the following changes in flight path in order of how effective they are in decreasing the centripetal acceleration, startingwith the least effective: A, decrease the turning radius by a factorof two; B, decrease the speed by a factor of three; or C, increase theturning radius by a factor of four.arrow_forward
