Question

plz answer fast
this is from maths ncert Ch4 pg.75 class 9th
also tell why we are using k in equation?????????​

Answer 1

Answer:

k is used to describe constant force

Step-by-step explanation:

let distance travelled by the body is x

and work done by the body be y

given that work done is directly proportional to distance travelled by the body

so we write equation as

Y = kx

here k is constant force

given constant force 5 units

I. e k = 5

so our equation becomes y = 5x
