1) On a distant planet in the universe, a rock is found to have a mass of 16kg and a weight of 124N. Using the weight formula, what is the rate of gravity’s acceleration on the new planet? (it is not 9.8m/s2, that is for Earth) 2) A student attaches two weights, 54N and 89N, to a string placed over a pulley. Find the acceleration of the system (be sure to show your work on finding masses and using Newton’s 2nd Law).

The extremely high temperatures needed to trigger nuclear fusion are proposed to be generated by laser irradiating a spherical pellet of deuterium and tritium fuel of diameter 1.8 mm. (a) determine the maximum fuel temperature that can be achieved by irradiating the pellet with 200 lasers, each producing a power of 550 w. the pellet has an absorptivity 0.3 and emissivity 0.8.
