Question

an object weighing 600 n is lifted 12m up from the ground . how much is done

Answer 1

Answer:

• 7200 Joules is the required answer .

Explanation:

Given:-

• Force ,F = 600 N
• Height ,h = 12m

To Find:-

• Work Done ,W

Solution:-

As we have to calculate the work done by the object in against gravity.

Work Done by the machine is calculated by the product of force & its height which is lifted up.

• W = Fh

where,

• W denote Work Done
• F denote Force
• h denote height

Substitute the value we get

→ W = 600 × 12

→ W = 7200 J

• Hence, the work done by the object is 7200 Joules.
