Q1. A car moving with an initial velocity of 27 m/s slows down at a constant rate of -2 m/s^2 for 3 seconds What distance does the car cover in the time?
Q2. What is the lift (in newtons) by reason of Bernoulli's principle on a wing of area 77 m^2 if the air passes over the top and bottom surfaces at speeds of 270 m/s and 140 m/s, correspondingly?
