Question

The kinetic energy acquired by a body of mass M
after travelling a fixed distance from rest under the
action of a constant force is


And = Independent of M​

Answer 1

Answer:

we know that :-

➖Acceleration=a = FM

➖ F = Constant force

➖M = Mass of the body

➖Velocity acquired after travelling a fixed distance

d : v=u²+2as

=2+2FMd

=2FdM

Kinetic energy acquired:KE

=12Mv²

=12M²FdM²

=12M²FdM

=Fd

so inversely proportional to mass m to the power 12
