Question

calculate the work done in pushing a cart through a distance of 50m against the force of friction equal to 250N also state the type of work done
​

Answer 1

Answer:

workdone =force ×displacement

=250×50=12500 N

Answer 2

Question:

Calculate the work done in pushing a cart through a distance of 50 m against the force of friction equal to 250 N, also state the type of work done.

Answer:

• The work done = 12500 joule (J)

• Positive work is done.

Given:

Displacement = 50 m

Force = 250 N

To find:

• The amouunt of woek done.
• The type of work done.

Explanation:

Displacement occured on the car by pushing it = 50 m.

Force applied against the cart = 250 N.

We know that,

Work done = (Force × Displacement)

                   = (250 × 50)

                   = 12500 Nm

                  = 12500 joule (J).

∴ 12500 joule(J) work is done.

Since, the car get displaced against the direction of the force applied on it. So, positive work is done.
