A skydiver is accelerating at 5.80 m/s' and the force of air resistance acting on her is 212 N. The mass of the skydiver is kq. (Record your 3-digit answer.) Use the following information to answer the next question. The engines of a rocket can be used to increase the speed of a spacecraft, but the rocket thrust takes a propellant. A gravity assist maneuver can greatly change the speed of a spacecraft without using up propellant, which can save significant amounts of propellant. A gravity assist maneuver uses the gravitational force exerted by celestial bodies on spacecraft to reduce Interplanetary travel times. Which of the following describes what happens to a spacecraft as a result of a gravity assist maneuver? 1. change in speed 2. change in direction 3. change in mass 4. change in acceleration (Record your values from lowest to highest) Note: You may not need to use all four spaces. Record your values with no spaces or commas between the numbers. Answer : The gravitational field strength of Venus is 8.9 N/kg. If its radius is 6.05 x 10" m, the mass of Venus, expressed in scientific notation, is a.b x 10""kg. The values for a, b, c, and d are , and
