A body is pushed giving it an initial velocity of 5ms-1 and comes to rest after travelling 4.9m. Find the co efficient of friction?

Question

Arun · Answer

from v 2 =u 2 +2as 0=5 2 +(-2a×4.9) a =2.55m/s 2 Now f k =ma. It is the only force acting in x direction. and normal reaction (R) =mg also f k = u*R, u*=f k /R putting values- u*=ma/mg u*=2.55/10 coff of friction (u*) =0.25
