Question

(b)A force of 10N acts on a particle of mass 0.4kg for 5 seconds. Find the acceleration of the


particle and its change in momentum in 5 secods.



​

Answer 1

Answer:

F=m×a

10= 0.4× a

a = 10/0.4

a= 25 ms^-2

Answer 2

force 10 n

mass 0.4 kg acceleration :? using the relation f= ma 10= 4/10×9 a= 100/4 =25 ms-2
