answer : the momentum of a man riding his bicycle downhill is 400 kg m/s.
mass of the man of bicycle = 40 kg
velocity of the bicycle = 10 m/s
momentum = mass × velocity = 40 kg × 10 m/s = 400 kg m/s
the momentum of a man riding his bicycle downhill is 400 kg m/s.
i believe the correct answer is option a. it decreases.
explanation: when the spacecraft takes off and moves farther away from earth, the gravitational pull would start to become less and less as the distance increases.
