45 тi/hr 1. The car is traveling at a speed of approaches point A. Beginning at A, the car as it decelerates at a constant 4 Jt/S until it gets to point B, after which its constant rate of decrease of 3 ft/s² as it rounds the interchange ramp. speed is Determine the magnitude of the acceleration of the car at point C. Use 1 mile = 5280 ft. Hint: you have to solve the tangential velocity at point C using UAM Formulas. 200' A В 300'

In a laboratory test of tolerance for high acceleration, a pilot is swung in a circle 15.0 m in diameter. It is found that the pilot blacks out when he is spun at 30.6 rpm (rev/min). At what acceleration (in SI units) does the pilot black out? acceleration: 77.01 m/s? Express this acceleration in terms of a multiple of g. acceleration as a multiple of g: 7.858 If you want to decrease the acceleration by 22.0% without changing the diameter of the circle, by what percent must you change the time for the pilot to make one circle? percent of time change:

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

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
