The work done is 150 joules
Explanation:
Work occurs when a force (F) acts on an object to move it some
distance (d) from the start point
→ Work done = F × d
The S.I unit of work is Joule
A force of 50 N is used to move a footstool 3 m
→ F = 50 N
→ d = 3 m
→ Work done = F × d
Substitute the values of F and d in the rule
→ Work done = 50 × 3 = 150 joules
The work done is 150 joules

Explanation:
Let the distance be 
, the time taken by P waves be 
and the time taken by the S waves be 
.
For the P waves,
For the S waves,
Equating the ,
Divide both sides of the equation by 500 to reduce the terms.
Since S waves arrive 2 minutes (= 120 seconds) after P waves,
Substitute this in the equation of the distance.
Substitute this in the equation for involving .
