Vector addition and speed 1. A goose is flying due South at 20 km/hr, the goose is flying into a 15 km/hr due North wind. What is the goose's resultant velocity?

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.

i believe the answer is electric potential.

explanation:

the ima (higher than 1m) will be greater than the ima with the height of 1m.
