A force of 200 N is exerted on an object of mass 40 kg that is located on a sheet of perfectly smooth ice. 1. Calculate the acceleration of the object.
2. If a second object identical to the first object is placed on top of the first object, what acceleration would the 200 N force produce?

Two friends are having a conversation. anna says a satellite in orbit is in freefall because the satellite keeps falling toward earth. tom says a satellite in orbit is not in freefall because the acceleration due to gravity is not 9.80 m/2 . who do you agree with and why?

Consider two metallic rods mounted on insulated supports. one is neutral, the other positively charged. you bring the two rods close to each, but without contact, and briefly ground the the neutral rod by touching it with your hand. show answer correct answer what would be resulting charge (if any) on the initially neutral rod
