The given data is listed below as,

• The mass of the honey jar is,$m=0.5kg$
• The distance at which the jar fall is,$d=1m$

The force exerted is the product of the mass of an object and the acceleration due to gravity (in the case of vertical movement of the object).

It is expressed as follows,

$F=mg$ ..(1)

Here, is the mass of the jar and is the acceleration due to gravity that is .

The work done is the product of the displacement of an object and the force exerted by the object.

For$F=0.5kg$ and$g=9.8m/s^2$ in equation (1).

$$\begin{gathered} F=\left(0.5kg\right)×\left(9.8m/s^2\right) \\ =4.9lgm/s^2×\frac{1N}{1kgm/s^2} \\ =4.9N \end{gathered}$$

Since the force is acting in vertical downward direction so, $F=-4.9N$and its vector representation is,$\stackrel{â‡\P Ä}{F}=\left\{0,-49,0\right\}N$ .

The equation of the work done on the jar is expressed as,

$W=Fd$

Here, F is the force acting and d is the distance of the jar.

For$F=4.9N$and $d=1m$,

$$\begin{gathered} W=\left(4.9N\right)×\left(1m\right) \\ =4.9Nm \\ =4.9Nm×\frac{1J}{1Nm} \\ =4.9J \end{gathered}$$

Thus, the force acting on the jar is and the work done by the force is $4.9J$.
