Acyclist has a momentum of 771.9 kg m/s. if her mass is 93 kg what is the speed of the cyclist?
a. 8.3 m/s
b. 12.1 m/s
c. 13.2 m/s
d. 4.4 m/s

Take 771.9 Kg M/s  because that's how fast she is moving and divide it by 93 kg because that is her force pushing down

771.9/93= 8.3

A. 8.3 M/s

P.s I changed my answer on the last question you asked so change that.

Is a  vector quantity  that refers to "the rate at which an object changes its position." imagine a person moving rapidly - one step forward and one step back - always returning to the original starting position. while this might result in a frenzy of activity, it would result in a zero velocity. because the person always returns to the original position, the motion would never result in a change in position. since velocity is defined as the rate at which the position changes, this motion results in zero velocity. if a person in motion wishes to maximize their velocity, then that person must make every effort to maximize the amount that they are displaced from their original position. every step must go into moving that person further from where he or she started. for certain, the person should never change directions and begin to return to the starting position.
