Abaseball has a momentum of 6.0 kg m/s south and a mass of 0.15 kg. what is the baseball’s velocity? show work

Momentum of an object is defined as product of mass and velocity

so it is given as

here it is given that

mass = 0.15 kg

momentum = 6 kg m/s

so by plug in values in the above equation

so its speed will be 40 m/s

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.
