1. A sports car travelling east at 48.0 m/s passes a trooper hiding at the roadside. The driver uniformly reduces his speed to 22 m/s in 4.10 s

a) Find the magnitude and direction of the car’s acceleration as it slows down
b) Calculate the distance traveled during the 4.10 s time interval



i want know how to get Vaverage=35?

  • fizik -

    Vaverage = (48 + 22)/2 = 35
