Physics

A small space probe, of mass 240 kg, is launched from aspacecraft near Mars. It travels toward the surface of Mars, whereit will land. At a time 20.7 s after it is launched, the probe isat the location 4.30Ã—10-, 8.70Ã—100, 0 m, at at this same time itsmomentum is 4.40Ã—102, âˆ’7.60Ã—10-, 0 kgâ‹…m/s. At this instant, the netforce on the probe due to the gravitational pull of Mars plus theair resistance acting on the probe is âˆ’7Ã—10-, âˆ’9.2Ã—100, 0 N.Assuming that the net force on the probe is approximately constantover this time interval, what are the momentum and position of theprobe 20.9 s after it is launched? Divide the time interval intotwo time steps, and use the approximation Vavg =Pf / m
