Question

a block of mass 2 kg is hanging over a smooth and light Pulley through a light string .The other and is pulled by a constant force 40J. The kinetic energy of particle increases 40J in a given interval of time. Then (g=10m/s²)​

Answer 1

Answer:

plz rewrite the full question it is incomplete

Explanation:

but i can help u to understand how it work

actually the difference between kinetic energy is nothing but workdone ,so here 40j increase meaning workdone is 40j ,

now,work done =force #displacement

and force = mass#gravitational acceleration(g)

here mass= 2kg ,g = 10m/s sqr

for answer plz complete tha question
