9. Consider a sphere of radius 3 meters. (15 pts) a. Assume it contains a source of heat releasing an energy (per unit of volume) of 6000 Joules/m3. What is the total energy content of the sphere? b. Suppose the sphere radiates 1000 W/m2from the surface, how long will it take to radiate off the energy found in (a)?

If a rock is thrown upward on the planet mars with a velocity of 12 m/s, its height (in meters) after t seconds is given by h = 12t − 1.86t2. (a) find the velocity of the rock after two seconds. m/s (b) find the velocity of the rock when t = a. 12−3.72a m/s (c) when will the rock hit the surface? (round your answer to one decimal place.) t = s (d) with what velocity will the rock hit the surface? m/s
