A ladder of length 10.0 meters is leaning against a wall. The vertical wall is frictionless while the horizontal surface is rough. The angle between the ladder and the horizontal surface is 50.0 degrees. If the mass of the ladder is 7.6 kg, what is the magnitude of the torque (in Nm) of the weight of the ladder measured with respect to the point where the ladder touches the vertical wall

Asled is being held at rest on a slope that makes an angle θ with the horizontal. after the sled is released, it slidesa distance d1 down the slope and then covers the distance d2 alongthe horizontal terrain before stopping. find the coefficient ofkinetic friction μk between the sled and the ground, assumingthat it is constant throughout the trip. find the coefficient of kinetic frictionμk. express your answer in terms of someor all of the variables d1, d2, and θ.
