Question

Venus has a mass of 4.86 1024 kg and a radius of 6.05 106 m.
(a) What is the acceleration due to gravity on Venus?
-------m/s2

(b) How much would a 5.22-kg person weigh on this planet?
------N

Answer 1

i think you need the gravitational constant for venus. a = G(4.861024)/ (6.05106)^2
a = GM/ r^2
for part b, f = ma, multiply the acceleration from part "a" by 5.22 to get that person's weight in newtons
