A 2.0 kg mass is released from rest at the top of a plane at 20 degrees above the horizontal. The coefficient of kinetic friction between the mass and the plane is 0.20. What will be the speed of the mass after sliding 4.0 m along the plane?

Step 1
Given: Mass (m) = 2.0 kg Angle (θ) = 20 degrees Coefficient of kinetic friction (μ) = 0.20 Acceleration (a) = g * sin(θ) - μ * g * cos(θ) Acceleration (a) = 9.8 * sin(20) - 0.20 * 9.8 * cos(20) Acceleration (a) ≈ 1.5092 m/s^2 Show more…

An object with a mass m slides down a rough 37° inclined plane where the coefficient of kinetic friction is 0.20. If the plane is 10 m long and the mass starts from rest, what will be its speed at the bottom of the plane?

a 2.0 kg block is projected down a plane that makes an angle of 20 degrees with an initial kinetic energy of 1.20 J. if the coefficient of kinetic friction between the block and the plane is 0.40, how will the block slide down along the plane before coming to rest?
