Demonstrates that the horizontal component of the velocity of a body thrown vertically upward from another body moving horizontally is the same as that of the body moving horizontally and independent of the vertical component of velocity. Thus, a ball ejected from the vertical barrel of the Ballistic Car moving with uniform velocity return back to its original position into the barrel. The apparatus consists of a heavy metallic barrel mounted vertically on an aluminium car. The car has plastic wheels with ball bearings to minimize friction. Spring - loaded piston arrangement with two compressions settings of spring for ejecting the ball to two different heights. Complete with steel ball and a lock -pin with cord. Comes with instructions.
