Nasa S Phoenix Spacecraft Landed On Mars On May 25th 2008 In Order To Avoid Crashing Down Onto The Surface The Spacecr 1 (147.5 KiB) Viewed 23 times

NASA's Phoenix spacecraft landed on Mars on May 25th, 2008. In order to avoid crashing down onto the surface the spacecraft deployed downward-facing thrusters. During one point of its descent the spacecraft was slowing down at a rate of 2.50 m/s2. The acceleration due to gravity on Mars is about 3.72 m/s2. At that time, was the magnitude of the force on the spacecraft due to the thrusters greater or smaller than the magnitude of the gravitational pull on the craft due to Mars? Explain your answer.
