Question

Q#2 A 2400kg satellite is in a circular orbit around the Earth.The satlite travells with a constant speed of 6.67*10power3m/s. Theradius of the circular orbit is 8.92*10power6 m (a) what istheacceleration of the satllite? (b) what is the orbital period ofthe satellite?(c) what is the magnitude of the gravitational forceexreted on the satellite by the Earth? Q#2 A 2400kg satellite is in a circular orbit around the Earth.The satlite travells with a constant speed of 6.67*10power3m/s. Theradius of the circular orbit is 8.92*10power6 m (a) what istheacceleration of the satllite? (b) what is the orbital period ofthe satellite?(c) what is the magnitude of the gravitational forceexreted on the satellite by the Earth?

Explanation / Answer

The acceleration is the centripetal acceleration: a =v2/R = 4.988 m/s2 The period T = 2R / v = 8402.7 s The magnitude of gravitational force is: F = ma = 2400*4.988 =11970 N
