Question

what must be the velocity of
moving body
that its
2 kg
g so that
K. E. is
25 J​

Answer 1

Answer:

v = 5 m/s

Explanation:

Kinetic energy is the half of product of mass and square of magnitude of velocity .

K.E = 1/2mv²

where m is mass and V is magnitude of velocity .

now,

K.E = 1/2 mv²

25 Joule = 1/2 x 2 x v²

v² = 25 m²/s²

Square root both sides

---> v = 5 m/s
