Question

a 10 kg object is subjected to two forces F,one vector = 16 icap - 11j cap and F,two vector = 8i cap + 18 j cap ,the magnitude of resultant acceleration in ms / square will be ?????????????????????????

Answer 1

Question 36815

We are given force vectors $\vec{F}_1(16, -11)$ and $\vec{F}_2(8, 18)$ . The net (resultant) force is $\vec{F}(24, 7)$ . The magnitude of this force is $F = \sqrt{24^2 + 7^2} = 25N$ . Hence, according to $2^{\text{nd}}$ Newtons law, magnitude of acceleration is $a = \frac{F}{m} = \frac{25N}{10kg} = 2.5\frac{m}{s^2}$ .
