Newton's Third Law and the Conservation of Question
Momentum:
4.
A green 6 kg ball is moving at 4 m/s. It collides with an
orange 4 kg ball that is not moving (v= Om/s). After the
collision the green ball stops moving (v=0 m/s). What is the
velocity of the orange ball after the collision?
Select one:
0 m/s
О
8 m/s

it has to be b, about 97 percent.

the only real purpose of sputnik 1 was to beat the us into space. we were getting close to launching a useful satellite, explorer 1 - which launched on january 31, 1958. the ussr had to beat that, so they launched sputnik 1 on october 4, 19

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.
