Aspacecraft is launched from the surface of the earth with a velocity of 0.600c at an angle of 50.0 above the horizontal, positive x-axis. another spacecraft is moving past with a velocity of 0.700c in the negative x direction. determine the magnitude and direction of the velocity of the first spacecraft

force tends to be low and long diustance masses are high

i believe the answer is a hope it and is correct

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.
