Answer to Question #252744 in Mechanics | Relativity for Soft Crest

Question

A body of a 6kg undergoes a Constant horizontal acceleration of 2 m² 2. Calculate the resultant horizontal force acting on the body. what will be the resultant force on the body when it moves with a uniform velocity of 5m/s?.

Answer 1

Given:

$m=6\:\rm kg$

$a_1=2\:\rm m/s^2$

$a_2=0\:\rm m/s^2$

The Newton's second law says

$F=ma$

Hence,

(1)

$F=6*2=12\:\rm N$

(2)

$F=6*0=0\:\rm N$
