Question

an object of mass 15 kg is moving with a uniform velocity 4 m per second what is the kinetic energy processed by the object

Answer 1

Kinetic energy = 1/2* m*v^2

=) 1/2 * 15*4*4 J

=) 120J.

Hope it's helpful to u.

Answer 2

KE = 1/2 m v2

Given:
m = 15 kg 

V = 4m/s
 
substitute these value in the equation to get the ans. :)
