Vectors Numerical

1) If all the energy contained in a 46-gram golf ball could be used, how long could it power one 100-wattt light bulb? Hint: Think about the "Equivalence" of "mass" and "energy" Data: t= E/P, where t=time (in seconds), E= energy (in Joules), and P = power consumption in "watts" Note Reduce your final result to "meaningful terms"
2) Vectors of force question is attached
3) Hubble Law: A distant galaxy is determined to be 150 million light years distant and moving away from us; using the Hubble law determine its velocity in terms of "0.XX.C"
4) Determine the binding energy in joules of a cobalt atom. Data: # of protons in the nucleus: 27. # of neutrons in the nucleus:32. Mass of cobalt atom: 97.958205 x 10^-27 kg
5) A subatomic particle known as a "pion" has an average life span of 2.6 x 10^-8 sec. How long does the particle exist from the perspective of the laboratory observer if the pion moves pas the observer at 0.67c?
