Define Kinetic Energy. Write expression for Kinetic Energy.A force of 12N acts on anobject of mass of 4kg in the state of rest for 3s. Calculate the kinetic energy acquired by theobject . FOR 5 MARK MIND THIS.​

Answer»

ANSWER:

The energy possessed by a body by virtue of its MOTION is called Kinetic Energy.

Explanation:

LET m be the MASS of an object and V be the velocity of an object  

So, Kinetic energy of the object , K=  

1/2  mv  

Force = mass × acceleration

F=10N

m=2kg

then,

a=  m/F  

=  2/10

=5m/s
