Physics 1A HW2 Solutions
Note: There are many methods to do many of these problems. I give only one for each. 1. Horizontal Cannon on a Cliff (a) The rocket's vertical position is given by y = H - gt2 /2, so the time tg it takes for the rocket to hit the

January 20, 2012 1. 1D Rocket A rocket's engines have failed, and it is in free fall from a height of 5000 m from rest. The pilot can reignite the engines, at which point the rocket's acceleration is 30 m/s2 upward. You can neglect a
Physics 1A HW1 Solutions
1. Geometric vs Componentwise Vector Addition (a) The question is essentially asking which of the choices are sufficient to uniquely specify the vector C. Knowing the magnitude and direction is sufficient for specifying C. As is k
