Robb Page 03-Feb-2010 Physics 140 Professor Stoddard Chapter 1 Problem 3 Ques. On Mars, the acceleration of gravity is 3.71 m/s2. What would a rocks velocity be 3 seconds after you dropped it on Mars?
For this example we will ignore any effects that may b
Robb Page 10-Feb-2010 Physics 140 Professor Stoddard Chapter 1 Problem 4 Ques. How far would a rock fall in 3 seconds if you dropped it on Mars? (See Problem 3).
We will overlook any effect of air resistance since it is deemed to be negligible in this exa
