An object slides down at the top of a hill starting from rest it takes 8 seconds to slide down 100 meters at an angle of 60. Then what will be the coefficient of kinetic friction?
a=g(sinα−μcosα),a=g(\sin\alpha-\mu\cos\alpha),a=g(sinα−μcosα),
h=at22,h=\frac{at^2}2,h=2at2,
μ=tanα−2hgt2cosα=1.09.\mu=\tan\alpha-\frac{2h}{gt^2\cos\alpha}=1.09.μ=tanα−gt2cosα2h=1.09.
