Question

below are the intervals of the speed of a person's bodyduring a chin-up versus time.
TIME                           VELOCITY .0s                                .0m/s .5s                                .0831m/s 1.0s                               .166m/s 1.50s                            .207m/s 2.0s                              .0m/s What is the magnitude of the average force exerted on the bodyby the arms during the first time interval? below are the intervals of the speed of a person's bodyduring a chin-up versus time.
TIME                           VELOCITY .0s                                .0m/s .5s                                .0831m/s 1.0s                               .166m/s 1.50s                            .207m/s 2.0s                              .0m/s What is the magnitude of the average force exerted on the bodyby the arms during the first time interval?

Explanation / Answer

   Acceleration   a   =   v/t   =   (v2   -   v1)/(t2   -   t1)   =   (0.0831- 0.0) / (0.5 - 0.0)    a   =   0.1662   m/s2    Force   F   =   m* a   =   ?    You will need mass of person.    Force   F   =   m* a   =   ?    You will need mass of person.
