Question

the kinetic energy K of a particle moving in a straight line depends upon the distance S as K = as2. the force acting on the particle??​

Answer 1

Answer:

$k = a {s}^{2} \\ \frac{1}{2} m {v }^{2} = a {s}^{2} \\ differentiate \: the \: equation \: from \: both \: sides$

●

$\frac{1}{2} m 2v.dv = 2as.ds$

●

$mv.dv = 2as.ds$

●

$v \frac{dv}{ds} = \frac{2as}{m}$

●ā=2as/m

Force =mass×acceleration

=m×2as/m

=2as

hope it helps
