An airplane with a speed of 97.5m/s is climbing upward at an angle of 50.0 degree. When the plane's altitude is 732 meter, the pilot releases a package.
a) Find the distance along the ground, measured from a point directly beneath the point of release, to where the package hits the earth.
b) Relative to the ground, find the angle of the velocity vector of the package just before impact.
For a standard production car, the highest road-tested acceleration ever reported occurred in 1993, Calculate the magnitude of the car's acceleration
In the Experiment, you calculated the ratios of the measured distances, i.e. the ratios of Effort Distance/Load Distance. How did your calculations compare to your expectations
