Question

an object is moving at uniform velocity , and it's kinetic energy is 2500 j if mass of object is 50 kg then find velocity​

Answer 1

Answer:

kinetic energy = 1/2 mv²

v² = 2 X kinetic energy / mass

v² = 2 X 2500 / 50

v² = 100

v= 10 m/s

Answer 2

Answer:

The velocity of an object is 10 m/s.

Explanation:

It is given that an object is moving at uniform velocity and it's kinetic energy is 2500 J, if mass of object is 50 kg.

Given,

Kinetic Energy of an object = 2500 J

Mass of an object = 50 kg

By using the formula of Kinetic Energy,

As we know that, Kinetic Energy is directly proportional to the mass of an object. Kinetic Energy is also directly proportional to the velocity of an object.

K.E. = 1/2 mv²

=> v² = 2 × K.E./m

=> v = √2 × K.E./m

=> v = √2 × 2500 / 50

=> v = √2 × 50

=> v = √100 m/s

=> v = 10 m/s

[ .°. v = 10 m/s ]

Therefore, the velocity of an object is 10 m/s.
