Question

a 3kg object is subjected to two forces together f1 =(6i-7j) N and f2=(3i+3j)N.the magnitude of resulting acceleration in m/s2 will be?

Answer 1

calculate the forces in the respective axis. then u can calculate acceleration in an axis by using the formula f=ma .. then calulate the resultant acceleration ( at this stage , you will be knowing acceleration in x and y axis).
