Hola User________________

Here is Your Answer.....!!!!!
_________________________

〽↖↖Actually welcome to the concept of the KINEMATICS OF A BODY ....

〽⤵Here given

〽⤵Mass = 12 kg

〽⤵Initial Velocity = 20 m/s

〽⤵Final Velocity = 80 m/s

〽⤵Time taken = 5 sec

〽↖↖.....Thus according to the concept of Newtons Second law of motion .....

〽⤵⤵FORCE = MASS × ACCELERATION. ...

〽⤵Thus here acceleration = v - u ÷ t

〽⤵=======》 a = 80 - 20 ÷ 5 =====》 a = 12 m/s^2 ....

〽↖↖thus. ... F = ma

〽↖↖F = (12) (12)
therefore we get

〽⤵⤵Force = 144 newtons ⚓

⤵F = 144 N....
