A satellite is in orbit around a planet.The orbital radius is 34.0 km and the gravitational acceleration at that height is 2.3 m/s².What is the satellite's orbital speed? A)280 m/s B)8.8 m/s C)28 m/s D)88 m/s

Question

Quizplus · Accepted Answer

The correct answer is A because the orbital speed of a satellite is given by the formula v = sqrt(r * g), where r is the orbital radius and g is the gravitational acceleration. Plugging in the given values, we get v = sqrt(34.0 km * 2.3 m/s^2) = 280 m/s.
