Two astronauts are taking a spacewalk outside the International Space Station. The first astronaut has a mass of 85.2 kg. The second has a mass of
65.4 kg. Initially, both astronauts have zero velocity relative to each other.
Then, the astronauts push against each other, giving the first astronaut a final
velocity of 1.2 m/s to the left. If the momentum of the system is conserved,
what is the final velocity of the second person?
O A. 1.6 m/s to the right
B. 1.6 m/s to the left
O c. 1.3 m/s to the left
O D. 1.3 m/s to the right

im not sure

Explanation:

i think its c if i'm wrong

force is based upon mass and acceleration.the statement is not always true.

it can be explained from newton's second law of motion.

as per newton's second law of motion the rate of change of momentum is directly proportional to the applied force and takes place along the direction of force.

mathematically it can be written as -

                                              ⇒      

here   k is the proportionality constant whose value is 1.

                                                            [a is the acceleration=dv/dt]

hence we see that force not only depends on mass and acceleration but also on velocity and rate of change of mass. force f will depend on mass and acceleration only when mass is constant.

hence the statement that force is based upon mass and acceleration is false.
