Question

A block of mass 10 kg starts sliding on a surface with an initial velocity of 9.8 ms^-1. The coefficient of friction between the surface and bock is 0.5. The distance covered by the block before coming to rest is: [use g = 9.8 ms^-2]

Accepted Answer

Correct answer: B. (b) a=−μ g=−0.5×9.8=−4.9 m/s^2 d= v^22 a= 9.8×9.82_(4.9_) =9.8m

$A block of mass 10 kg starts sliding on a surface with an initial velocity of 9.8 m s^{- 1} . The coefficient of friction between the surface and bock is 0.5. The distance covered by the block before coming to rest is: [use g = 9.8 m s^{- 2}]$
