Question

A horizontal force of 150 N produces an acceleration of 2 m/s2 in a body placed on a horizontal surface .A horizontal force of 200 N produces an acceleration of 3 m/s2 .The mass of the body and coefficient of kinetic friction are (g=10ms-2)

Answer 1

150=2m+10*mu*m. 200=3m+10*mu*m. divide and cross multiply. mu=0.1. substitute. 150=2m+m. m=50 kg
