Question

If the work done by a force applied on a body is directly proportional to the distance travelled

by the body, express this in the form of an equation in two variables, taking the constant force as

3 units. Also read from the graph the work done when the distance travelled by the body is –

i) 0 unit ii) 2 units
​

Answer 1

Answer:

please mark me as brainliest please

Step-by-step explanation:

0 2 3

y 0 5 10

Let x units be the distance traveled by the body and y units be the work done by constant force.

According to problem, y=5x ...(1)

Now , putting the value x=0 in (1)

y=5×0=0

So, the solution is (0,0)

Putting the value x=1 in (1)

y=5×1=5

So, the solution is (1,5)

Putting the value x=2 in (1)

y=5×2=10

So, the solution is (2,10)

(i) When x=2 units (distance)

Putting the value x in (1)

y=5x

y=5×2=10.

Hence, Work done =10.

(ii) When x=0 units (distance)

Putting the value x in (1)

y=5x

y=5×0=0.

Hence, work done =0.
