Question

A force of 5n acts on a body of weight 9.8n. what is the acceleration produced in 2 m/s ?

Answer 1

Therz no opposing force
so,
f=ma
5=1×a (given weight=9.8 so mass=1)
5=a

therefore acceleration=5 m/s^2

Answer 2

Explanation:

It is given that,

Force acting on the body, F = 5 N

Weight of the body, W = 9.8 N

The weight of an object is equal to the mass of the body multiplied by the acceleration due to gravity as,

W = m × g

$m=\dfrac{W}{g}$

$m=\dfrac{9.8\ N}{9.8\ m/s^2}$

m = 1 kg

Let a is the acceleration produced in the body. It is given by

$a=\dfrac{F}{m}$

$a=\dfrac{5\ N}{1\ kg}$

$a=5\ m/s^2$

Hence, this is the required solution.
