Best ResponseYou've already chosen the best response.1First find a using v=u+at Here vfinal velocity(in this case 0.500m/s) uinitial velocity(in this case 0m/s) ttime taken(in this case 2.0s) aacceleration Then find the magnitude of the force using F=ma mmass aacceleration

Best ResponseYou've already chosen the best response.0a=v/t. so .5/2 = 1. f=m*a so f=(20)*(1) = 20 N

Best ResponseYou've already chosen the best response.0v=u+at v/t = a a = 0.5/2 = 1/4m/s^2 f=ma = 20*1/4 = 5N
