Question

If the work done by a body on application of a constant force is directly proportional to the distance travelled by the body, express this in the form of an equation in two variable and draw the graph of the same by taking the constant force as $5$ units. Also read from the graph the work done when the distance travelled by the body is
$\left(i\right)$ $2$ units
$\left(ii\right)$ $0$ units

Answer 1

Given,

Here x is distance travelled and y is work done.

$y=5x$

(i) 2 units

When distance, $x=2$

So, $y=5\left(2\right)=10$

Therefore work done = 10 units

(ii) 0 units

When distance, $x=0$

So, $y=5\left(0\right)=0$

Therefore work done = 0 units
