An astronaut exploring a distant solar system lands on an unnamed planet with a radius of 4880 km. When the astronaut jump upward with an initial speed of 2.19 m/s, she rises to a stage of 1.08 m. What is the mass of the planet?
kg
Answers:
Lets calculate Gravity acceleration fo the planet .
V^2=2as+(U)^2
V is final velocity = not anything.
a= acceleration .
s= height = 1.08
U intial velocity = 2.19 ms^-1
(0)^2=2(a)(1.08)+(2.19)^
a=-2.22041667ms^-2
Gravitational Field strenght =2.22041667 N/Kg
F=GM1M2/R^2
F=weight .
M1 is mass of unnamed palnet
M2 freight of the astoranot .
R is the radius .
M2X(2.22041667)=(6.67*10^-11)(M1)(M2)/...
M2= 7.92771974*10^23 Kg.
approx. 7.93*10^23 Kg.
Damn it how did you get my address?
