Star s has a second planet y. this planet has two moons that move in circular orbits around the planet. moon 1 has mass m1 = 1.8 × 1018 kg, orbital radius r1 = 5.2 × 1011 m, and speed v1 = 2400 m/s. moon 2 has a mass m2 = 0.85m1 and orbital radius r2 = 0.35r1.what is the speed of and moon 2, v2, in terms of v1? v2 = 0.122 v1v2 = 1.69 v1v2 = 0.35 v1v2 = 0.592 v1v2 = 2.43 v1v2 = 2.86 v1

here we know that ball will drop down by total distance 3.2 m

so here we know that

now using kinematics

now in the same time it will cover horizontal distance of 0.75 m

so speed of the ball will be

close lines strong magnet less close weaker

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
