2D Kinematics

2d Kinematics Glogster Project 

Answers to Practice Problems Ch.3............................................. 1. x=5.85m 2. V=5.56m/s 3. y=236.68m 4. Vx=12.31m/s This doesn't make sense because V=2.4m/s and it should be greater since the height that the boy threw the balloon is 8m high. In actuality V= should be greater than 2.4 m/s.
