Question

A body of mass 3kg retards uniformly from 40m/s to 10m/s in 10s.find the retarding force.?please reply soon.....

Answer 1

Retarding force is calculated as follows:

F=mass x acceleration....(acceleration is change in velocity with time = 40-10)
                                                                                                                     10
 = 3k(40-10)    =  3 x 30/10 =   3 x 3 = 9N
           10

Therefore the retarding force= 9Newtons
