An object of mass 31 kilograms is on a smooth horizontal plane and a force of

124 Newtons is applied to the object in a horizontal direction (friction is zero).

The object is initially at rest. Calculate

(a) the acceleration of the object 

(b) the velocity of the object after 5 seconds 

(b) the kinetic energy of the object after it moves 14 metres.
