Questions
A marble block of mass 2 kg lying on ice when given a velocity of 6 is stopped by friction in 10s. Then the coefficient of friction is (g = 10 )
detailed solution
Correct option is C
0 = u - at ⇒ u = at = µg.tμ=vgt=610×10=0.06Talk to our academic expert!

A skier starts from rest at point A and slides down the hill without turning or breaking. The friction coefficient is . When he stops at point B, his horizontal displacement is s. What is the height difference between points A and B?
(The velocity of the skier is small, so that the additional pressure on the snow due to the curvature
can be neglected. Neglect also the friction of air and the dependence of on the velocity of the skier.)
