determination of the acceleration of an elevator.
... DETERMINATION OF THE ACCELERATION OF AN ELEVATOR. INTRODUCTION: In order for an object to accelerate, there must be a net force acting on it. We know that the direction of the acceleration will be in the same direction as the direction of the net force. The equation for Newton’s 2nd law is F = ma o ...

... The terminal speed of a ski diver is 160 km/h in the spread eagle position and 310 km/h in the nosedive position. Assuming that the diver’s drag coefficient C does not change from one point to another, find the ratio of the effective cross sectional area A in the slower position to that of the ...
