An Airbus A320 jetliner has a takeoff mass of 75000 kg. It reaches its takeoff speed of 82 m/s (180mph) in 35s . For rubber rolling on concrete, Ur=0.02. This is needed for the equation. You can neglect air resistance but not the rubber rolling on concrete. What is the thrust of the engines?

Amanometer is used to measure the air pressure in a tank. the fluid used has a specific gravity of 1.25, and the differential height between the two arms of the manometer is 34 in. if the local atmospheric pressure is 12.7 psia, determine the absolute pressure in the tank for the cases of the

You are driving to the grocery store at 20 m/s. you are 110m from an intersection when the traffic light turns red. assume that your reaction time is 0.50s and that your car brakes with constant acceleration. how far are you from the intersection when you begin to apply the brakes? what acceleration will bring you to rest right at the intersection? how long does it take you to stop after the light changes? the known values: vi=20m/s xi=110m t=.50s vf=0m/s xf=0m a=?
