Horizontal Projectile Motion Physics Name: 1) In the absence of friction, explain why the horizontal component of a projectile’s velocity is a constant. 2) A marble is shot horizontally from a tabletop with an initial speed of 2.5 m/s using a marble launcher. If the table is 0.8 m high, how far will the marble travel along the floor before it lands? 3) A cyclist jumps off a low cliff at an initial velocity of 18 m/s. The cyclist travels 16.6 m before touching down. How high is the cliff? .
