Question

A boy pushes a box at rest of mass 10 kg with acceleration of 0.1 m/s². If he do a work of 10 J. Find how much he has displaced the box.

Answer 1

To find :

displacement of the box

Given :

• mass of box , m= 10 kg
• acceleration , a= 0.1 m/s²
• work = 10 J

$\large \underbrace{ \bold{formula \: to \: be \: used}}$

• Force = m×a
• work = F × s
• displacement, s = W/F

$\large \underbrace { \bold{solution}}$

Mass = 10 kg

acceleration = 0.1 m/s²

hence, Force = m×a

$\implies \bold{force \: = 0.1 \times 10kg} \\ \implies \boxed{ \boxed{ \bold{force = 1 \: newton}}}$

Displacement = Work/Force

$\implies \bold{displacement \: = \frac{ \cancel{10}}{ \cancel{01}}} \\ \implies \boxed{ \boxed{ \bold{displacement = 10}}}$

hence, Displacement = 10 m

Answer 2

Answer:

Explanation:

To find :

displacement of the box

Given :

mass of box , m= 10 kg

acceleration , a= 0.1 m/s²

work = 10 J

Force = m×a

work = F × s

displacement, s = W/F

Mass = 10 kg

acceleration = 0.1 m/s²

hence, Force = m×a

Displacement = Work/Force

hence, Displacement = 10 m
