Question

A student is helping to push his mother heavy shopping cart with a force of 50N for 150m .what is the amount of work done?

Answer 1

Answer:

7500 joules

Explanation:

Given :

• Force with which the shopping cart is being pushed = 50 Newtons

• Displacement of the cart = 150 metres

To find:

• Amount of work done in displacing the shopping cart

Work done = Force × Displacement

Work done = 50×150

Work done = 7500 joules

The work done by the student and his mother is equal to 7500 joules

Values shown : The values shown by the student are kind and helping his mother to push the cart easily

Answer 2

$\underbrace{\bf{Work=Force.Displacement}}$

• It is dot product
• SI units of work is N-m
• N-m = Joules

Work is defined as " dot product of force and displacement "

Given ,

A student is helping to push his mother heavy shopping cart with a force of 50 N for 150 m.

Force , F = 50 N

Displacement , s = 150 m

⇒ Work = F . s

⇒ Work = 150 . 50

⇒ Work = 7500 Joules

So , Amount of work done is 7500 Joules .
