Hi all, I am just beginning Physics, and have 2 simple problems but don't know how to go about solving them. Here goes: 1) An eagle is flying due east at 8.9 m/s carrying a gopher in its talons. The gopher manages to break free at a height of 12 m. What is the magnitude of the gophers velocity as it reaches the ground? What formula is used to do to calculation? This is a multiple choice question, but using the Pythagorean Theorem doesn't yield any of the choices. The choices: 8.9 m/s, 9.8 m/s, 11 m/s 18 m/s or 22 m/s? 2) A projectile is fired from a gun and has initial horizontal and vertical components of velocity equal to 30 m/s and 40 m/s, respectively. Determine the initial speed of the projectile. Again, what formula is used to do to calculation?
