a person with a mass of 106kg has a weight of 1060n

grav force prop 1/r squared 2r all squared is 4rsquared 1/4rsquared quartered

we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is

after 28s,

m/s

which i would round to 150 m/s as my final answer
