Asolid sphere of uniform density starts from rest and rolls without slipping down an inclined plane with angle θ = 30o. the sphere has mass m = 8 kg and radius r = 0.19 m . the coefficient of static friction between the sphere and the plane is μ = 0.64. what is the magnitude of the frictional force on the sphere?
i got 21.168n and the computer told me i was wrong because i was trying to find force of the max static instead of the actual static force. !
