Question

an object of mass 6 kg is sliding on horizontal surface with a uniform velocity of 8m per second assume force of friction offered by the surface to be zero the force required to maintain the motion of object with the same uniform velocity is

Answer 1

$\red{HEY\:BUDDY!!}$

HERE'S THE ANSWER...

_______________________________

♠️ Here the body is moving with the constant velocity of 8 m/s , So

⏺️$\red{Acceleration\:is\: zero ( 0 )}$

♠️ We know force is product of mass and Acceleration

=> Force = Mass × Acceleration

=> Force = 6 Kg × 0

=> $\boxed{ Force\:=\:0}$

▶️ So no force is required , it will keep moving with that constant velocity

♠️ Extra knowledge , to prove this answer

▶️ $\blue{ Newton's\:first\:law\:of\:motion}$

=> A body doesn't chance it's state untill an external force acts on it .

Answer 2

Answer:

the answer is clearly 0 N.

Explanation:

as we know f =m×a and the acceleration definitely 0 as the frictional force is acting,

so f=6×0

0 N.

dosto it doesn't matter that what is the distance and time of you find a frictional force so the answer will definitely 0 N
