Calculate the average acceleration of a car that changes speed from 0 meters per second to 15 meters per second in 5 seconds

An object has a weight of 500 on earth what is the mass of this object

What do elements in a family tend to share. a.) similar periods b.) similar groups c.) similar atomic symbols d.) similar chemical properties and characteristics

Two objects of different mass start from rest, are pulled by the same magnitude net force, and are moved through the same distance. the work done on object 1 is 900 j. after the force has pulled each object, object 1 moves twice as fast as object 2. how much work is done on object 2?
