Question

Calculate Kinetic energy of a 2kg body moving at 10ms-1​

Answer 1

Answer : ➥ Kinetic energy of the body (K.E) = 100 J.

Given : ➤ Mass of the body (m) = 2 kg. ➤ Velocity of the body (v) = 10 m/s.

To Find : ➤1Kinetic energy of the body (K.E) = ?

Solution : As we know that. Kinetic energy of a body.

Answer 2

Answer:

Given:

Mass of body(m) = 2Kg

Velocity of the body (v) = 10m/s

To find :

1 kinetic energy of the body (K.E)

Sol:

Kinetic energy of the body

:----> K.E= 1/2 mv2

:----> K.E = 1/2×2(10)2

:----> K.E= 1/2×2×10×10

:----> K.E = 1×10×10

:----> K.E = 10×10

:----> K.E=100

Hnece, the kinetic energy of the body is 100J
