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 variables 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:

(i) 2 units

(ii) 0 units

(class 9th exercise 4.3
question 6.)​

Answer 1

Answer:

Step-by-step explanation:

Given,

Here x is distance travelled and y is work done.

y=5x

(i) 2 units

When distance, x=2

So, y=5(2)=10

Therefore work done = 10 units

(ii) 0 units

When distance, x=0

So, y=5(0)=0

Therefore work done = 0 units
