Question

2.) A body of mass 0.5kg moves with a constant
velocity of 2m/s - What is the work done to bring it
to the distance of 2m.
​

Answer 1

Answer:

According to law of conservation, Work Done = Change in kinetic Energy

Explanation:

w=∆KE=1/2Mv^2=1/2×(0.5)×2^2=1j

hope this helped you plzzz brainliest me

Answer 2

Answer:

As it moves with constant velocity hence acceleration is zero

There work done will become zero
