Question

Calculate the work done in pushing a cart through a distance of 15m against the force of friction equal to 250N.​

Answer 1

Answer:

3750J

Explanation:

w=F.Scos@

as F and S are in same direction

@=0

cos@=1

w=250x15=3750J

Answer 2

Answer:-

★ Given:-

• Distance = 15 m.

• Force = Friction = 250 N.

★ To Find:-

• Work done

★ Formula Used:-

• Work done = F × d

Here;

▪︎F = Force

▪︎d = displacement

★ Solution:-

⫸ As we know,

⍟ Work done = F × d

⫸ Here,

Object is pushed straightly;

So here,

⍟ Distance = Displacement

⫸ Putting the given values in formula,

❀ Work Done

= Force × Displacement

= 250 × 15

= 3750 Joule

∴ Work done is 3750 Joule
