A: Small rockets are used to make tiny corrections to the velocity of a satellite. If a rocket has a thrust of 35 N and is used to change the velocity of a 72000 kg satellite by 0.63 m/s, for how long (time) should it be fired?
B: A 2-kg pumpkin flies through the air at 42 m/s (93mph)! It strikes a 500kg Volkswagen Bug that has been abandoned in a corn field for quite some time. The pumpkin bounces off the car and has a final velocity of -2.68 m/s (-6.0 mph). What is the final velocity of the car?
