An airplane reaches its takeoff speed of 60 m/s with constant acceleration in 30 s, starting from rest. The time it takes to go from 40 m/s to 60 m / s is: A car starts moving from rest with an acceleration of 0.40 m/ s2. A minute later the acceleration stops, and the car moves with constant speed for 5.0 minutes. The car's brakes are finally applied and stops in 2.0 minutes slowing evenly. The total distance traveled by...
