Slowing Down: The speed of an object moving through a viscous fluid is given by u (t) = A • e-bl(a) If the numerical value of A (in Sl units) is 8.40 and the numerical value of b (in Sl units) is 1.12. then what is the initial acceleration of the particle, at time + = 0?(b) How far does the particle move in the first 4.00 s?You may ignore gravity. The particle has the same density as the fluid.
Your friend wants to show off how quickly their car can accelerate. So you get in and they start driving. You notice that the pine tree scented air freshener that hangs from the rear view mirror makes an angle of 26.5 degrees with respect to the vertical (straight down) direction while the car is accelerating. Using this angle, you pull out your calculator and find the car's acceleration. The answer is:
