Unit 3: Motion in Two-Dimensions

Problem Set C

 

Problem 16:

Two objects are initially the same height above the ground. Simultaneously, one is released from rest and the other is shot off horizontally with an initial speed of 2.36 m/s. The two objects collide after falling 17.2 m. How far apart (in meters) were the objects initially?

 

 

 

 

 

 

 

A discussion of the formulae for projectile motion and of the basic strategy for solving such problems is provided on the Set C Overview Page.

Detailed information about and discussion of the strategies for solving horizontally launched projectile problems is provided online at The Physics Classroom.
