Question

An object or mass 10 kg is moving with uniform velocity of 3m/s. What is the kinetic energy possessed by it?​

Answer 1

Answer:

45J

Explanation:

K.E = 1/2 * m* v^2

= 1/2*10* 3^2

= 1/2*10* 9

=45J

Answer 2

Answer:

45 J

Explanation:

Given,

Mass ( m ) = 10 kg

Velocity ( v ) = 3m/s

To find : Kinetic energy ( K.E ) = ?

Formula : -

K.E = ( 1 / 2 ) mv^2

     = ( mv^2 ) / 2

     = ( 10 x 3^2 ) / 2

     = ( 10 x 9 ) / 2

     = 90 / 2

K.E = 45 J
