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: 77.0 m/s² Express this acceleration in terms of a multiple of g. acceleration as a multiple of g: 7.86 8 If you want to decrease the acceleration by 24.0% 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: %

Erza is running her wagon on straight road while chasing Natsu at 200.0 kph. After driving for some time, Erza approaches a curve causing her to tum 180.0 deg then drives straight again. Assume that the curved part of the roadis an arc of a circle with radius of 13.00 m. Speed is constant throughout the travel. A. What is the acceleration's magnitude, in m/s^2, 6.981 s after leaving the curve? B. What is the angular speed, in rpm, while on the curve?

Q2. A drone is used to spray pesticide in a farm. It covers (d1=30 m) towards south. Then it flies (d2=40 m) in a direction 350 east of south, then by changing its direction it covers a distance of (d3=50m) in the direction 650 east of north and finally it covers a displacement (d4=65m) in a direction of 300 south of west. Calculate total displacement (d) covered by the drone and its direction.
