One soccer player (m1 = 65kg) is traveling with a velocity of v1 = (4.5 j) m/s. this player collides with a second player who has a mass of m2 = 72 kg who is traveling with a velocity of v2 = (3.3 i - 2.2 j) m/s. the players tangle together when they collide (a totally inelastic collision). what is the speed of the combined mass just after the collision? give your answer in unit vector notation.

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).

what is the actual question though?

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.

the answer to this is proletariats.

hope this : )
