Question

what must be the velocity of moving body of mass 2kg so that it's kinetic energy is 25J

Answer 1

We know that Kinetic energy, K.E.=1/2mv

=> 25 J = 1/2 x 2 x v

=> v = 25  

=> therefore, v = 5 m/

hope these is helpfull

and please mark me as brainlist

ANSWER :

─━━━━━━⊱✿⊰━━━━━━─

The mass of the object, m = 2 kg

The speed of the object, v = ?

The Kinetic Energy, K.E = 25 J

We know that ,

$kinetic \: energy = \frac{1}{2} mv ^{2}$

From this ,,,

Kinetic Energy ,K.E = 1/2 × 2 × (v)^2

25 = (v)^2

v = 5 m/s

The Velocity is 5 m/s
