Question

A body of mass 10 kg is moving with an initial speed of 20 m/s. The body stops after 5 s due to friction between body and the floor. The value of the coefficient of friction is: (Take acceleration due to gravity g = 10 ms^-2)

Accepted Answer

Correct answer: D. (d): a=- μg ∵v=u+ at 0=20+(- 10) 5 50 =20 = 25=0.4

$A body of mass 10 kg is moving with an initial speed of 20 m/s. The body stops after 5 s due to friction between body and the floor. The value of the coefficient of friction is: (Take acceleration due to gravity g = 10 m s^{- 2})$
