Question

m = 0.25 kg , v = 2 m/s kinetic energy (K.E) =​

Answer 1

Answer:

We know that kinetic energy =

1/2 mv²

= 1/2(0.25)(2)²

= 1/2(0.25)(4)

= 1/2(1)

= 1/2

= 0.5

Ans: 0.5 kg.m/s

please mark my answer the brainliest

Answer 2

Answer:

(ke) =1/2mv²

=1/2×0.25×(2) ²

= 1/2×0.25×4

=1/2 ×1

Ans =0.5joules
