Exploration of the planet Mars uses robotic probes because the conditions 2. If the momentum of an object is quadrupled and the mass is halved while 7.

One mission to the direction changes from west to east, the velocity will have changed Mars used parachutes and airbags to bring a landing unit safely to rest on by a factor of 1. scalar 5. sun the planet's surface.

Record all four digits of your answer: a, b, c, d Velocity of landing shit just before it hit the surface. positive eight Velocity of landing the surface. the firif time 10 mov/k, up 1. An Olympic four-man bobsled travelling at 148.3 km/h [N] has a momentum of 2.59 x 10* kg.m/s [N]. What is the mass of the bobsled? 1.07 x 106 kg 629 kg O1.59 x 103 kg 390 kg 5. A 0.0380 kg model rocket is mounted on a nearly frictionless horizontal rail for testing purposes and a 0.0964 kg rocket engine is placed in the model. The rocket engine is designed to give a constant thrust of 13.8 N for the 0.856 s burn, until the mass of the engine is reduced to 0.0080 kg and it flames out. 3. The magnitude of the momentum of the landing unit as it entered the Martian atmosphere was Using momentum to analyze the above scenario is superior to using the Fnet = ma form of Newton's second law mostly because O2.16 x 103 kg-m/s Oacceleration is not given. O2.40 x 105 kg-m/s O force is not given. 04.40 x 103 kg-m/s time is a factor. 07.20 x 10* kg-m/'s both the mass and velocity change. 4. The magnitude of the impulse experienced by the landing unit during its first collision with the surface of Mars was 6.
