Question

A force of 5n acts on a body of weight 9.8 n,what is the acceleration produced meter-sec²

Answer 1

Force = mass * Acceleration

Weight = Mass * Gravity
9.8 = M * 9.8
Mass = 1 kg

5 = 1 * a
a = 5 m /s^2

Answer 2

The determined acceleration produced by the force in it is $\bold{5 \ m s^{-2}}$

Given:

Force = F = 5n  

Body weight = 9.8n

To find:

Acceleration = ?

Solution:

According to the newton's first law of motion,

$F=m a$

[Force is defined as the product of mass and acceleration]

Here,  

F refers to the force (5n), m refers to mass, a refers to acceleration

$g = 9.8 \ ms^{-2}$

$\mathrm{m}=\frac{9.8}{g}=\frac{9.8}{9.8}=1$

$F = ma$

Hence, the Acceleration is,

$a=\frac{5}{1}=5 \ m s^{2}$
