Question

160joule work is done when a force of 20N acts on the objects. Calculate the distance through which the object moves and also state in which direction it will move.​

Answer 1

Given

• Work = 160 J
• Force Applied = 20 N

To Find

• Distance covered and the direction in which the body moves

Solution

● Work = Force × Displacement

● If the work done is positive then the body moves in the direction of force and if the work done is negative then the body moves against the force.

✭ Distance Covered :

→ Work = Force × Displacement

→ 160 = 20 × Displacement

→ 160/20 = Displacement

→ 16/2 = Displacement

→ Displacement = 8 m

• As the work and the distance covered are positive then the body would move along the direction in which the force is applied

Answer 2

$\huge{\boxed{\bold{Question}}}$

160joule work is done when a force of 20N acts on the objects. Calculate the distance through which the object moves and also state in which direction it will move.

Given::

•Work Done =160J

•Force Applied=20N

To find

•Calculate the distance through which

the object.

moves and state its direction.

$\huge{\boxed{\bold{Añswer}}}$

•Distance(S)=8m

Calculation

Work done =F×s=FS cosx

•x is the angle between F and s vector.

x=0°(As it in straight line)

•Since no angle is given ,avoid

work done =Fs cosx

So,

Work done =F×s

=160J=F×s

=160J=20N×s

=S=160J/20

=S=8m

hence,

Distance (S)=8m
