The dwarf planet Haumea has a mass 0.0007 times that of the Earth and a diameter on average 0.11 times that of the Earth. What is the escape velocity of Haumea (in m/s)? (type in the numerical answer and unit, e.g. 10m/s.)
Find the escape speed (in m/s) of a projectile from the surface of Saturn.
An asteroid closely passes the Earth at a range of 17200 mi and relative speed of 7.8 km/s. The diameter is estimated at 30 m with a specific gravity of 3. If this asteroid had impacted Earth, how much energy would have been released? Express this quantity in units of mega- tons (Mton) where a megaton is the energy released by one million metric tons of TNT explosive. A metric ton is 1000 kg and the explosive energy density of TNT is 4184 J/g. Hint: If the asteroid hits the Earth, its relative velocity becomes zero. Ignore any change in asteroid velocity due to gravitational acceleration or air resistance.

- Titan has a very thick atmosphere of nitrogen gas at a surface pressure (P) of 150 kiloPascals (kg·m/sec2/m2 units). If pressure (P) is force per unit area, then the mass pushing down over 1 square meter of the surface will scale as P/g with g (1.352 m/sec2) being the surface acceleration due to gravity. Considering that the density of solid nitrogen is 1027 kg/m3, calculate the layer thickness of solid nitrogen that would result from freezing the atmosphere by dividing the density of nitrogen into the mass per m2? answer choices 108 meters 10.08 meters 1.08 kilometers 1.08 metersarrow_forwardThe escape velocity from the surface of planet A is 5700 m/s.
