Question

Two forces(10î+j^) and(6î+10j^)N act upon body of mass 8kg.Then acceleration of the body

a.(2î+3j^)ms-²
b.(3î+2j^)ms-²
c.(5î+6j^)ms-²
d.(2î+6j^)ms-²​

Answer 1

Answer:

mass of the body = 8 kg

Given Forces

A = (10i + j)N

B = (6i + 10j)N

Net force = A + B

= 10i + j + 6i + 10j

= 16i + 11j

$a = \frac{f \: net}{a} \\ a = \frac{16i + 11j}{8} \\ a = (2i + \frac{11}{8} j)m {s}^{ - 1}$
