Explanation:
(b) A uniform beam 150cm long weighs 3.5kg and
supported on knife-edges at its ends. The beam
supports a weight 7kg at a distance 30cm from
one end. Find the reactions of the supports.
The amount of work done during the kick is 200 Joules.
<h3>Formula for Work done </h3>
The formula for work done is Force× Distance
This is represented by fd
The force applied is 1,000 Newton
The displacement exerted by the force during kicking is 0.2meter
From this we can get the work done which is:
W= fd
= 1000N × 0.2m
= 200 Joules.
