An object 2.5kg is released from a height of 5m above the ground. Calculate the velocity of the object just before it strikes the ground.

How have the competing explanations' experiments on atoms affected the development of the atomic model?

Use the information presented in the graph to answer the questions. which segments show acceleration? which segment indicates that the object is slowing down? what is the velocity of segment b? what is the acceleration of segment b?
