A 540 kg satellite moves through deep space with a speed of 27 m/s. A booster rocket on the satellite fires for 1.4 s, giving a force to the satellite. The speed of the rocket increases to 31 m/s. Calculate the force given by the booster rocket to the satellite. (Assume that the mass of the satellite remains constant.) A)1543 N
B)2160 N
C)11,957 N
D)3024 N
