Question

The kinetic energy of mass 4 kg and momentum of 4 kg m/s is ​

Answer 1

Answer:

Given : m = 4 kg p = 6 NsKinetic energy K = p^22m K = 6^22 × 4 = 4.5 J

pls mark me brainest

Answer 2

$\small\boxed{\fcolorbox{pink}{crimson}{AnSwEr:-}}$

momementum=mass×velocity

4= 4×v

$velocity = \frac{4}{4} = 1m/s$

$kinetic \: energy= \frac{1}{2} m \times {v}^{2}$

$\frac{1}{2} \times 4 \times 1$

2×1= 2 KJ
