The escape speed from an object is v2 = 2gm/r, where m is the mass of the object, r is the object's starting radius, and g is the gravitational constant 6.67 × 10-11 m3 kg-1 s-2. what is the approximate escape speed, in km/s, from the solar system starting from an orbit at 1.0 au? in this case, the mass of the sun, 2.3e+30 kg, can be used as the mass of the solar system

Answer: it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.explanation:   we have equation of motion ,where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.average velocity = displacement/ time taken.average velocity = 10.69 miles/hr = 10.69*1.6*1000/(60*60) = 4.75 m/s4.75 = s/ts = 4. 1we also have acceleration = 2.18 m/s², initial velocity = 0 m/sso it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.
