20. As shown in Figure AP8.20, a green bead ofmass 25 g slides along astraight wire. The lengthof the wire from point@ to point ® is 0.600 m,and point A is 0.200 mhigher than point . Aconstant friction force(BFigure P8.20of magnitude 0.025 0 N acts on the bead. (a) If thebead is released from rest at point @, what is its speedat point ®? (b) A red bead of mass 25 g slides along acurved wire, subject to a friction force with the sameconstant magnitude as that on the green bead. If thegreen and red beads are released simultaneously fromrest at point @, which bead reaches point 8 with ahigher speed? Explain.

Part a: The potential energy of the bead at point A is converted into kinetic energy at point B but…

A 145 kg crate slides down a ramp, starting from rest. The ramp is inclined at an angle of 20.6 degrees with respect to the horizontal and has a height of 1.74 m. The crate is placed on frictionless casters so that it slides down the ramp without friction. What is the final speed of the crate (in m/s) just as it reaches the bottom of the ramp? Use g = 9.81 m/s?.

A 2.0kg block starts with a speed of 10. m/s at the bottom of a plane inclined at 35° to the horizontal. The coefficient of sliding friction between the block and the plane is 0.30. use the work-energy theorem to determine how far the block slides along the plane before momentarily coming to rest. I know the answer is 6.2, I just don’t know how to get to it.
A ball moves on a frictionless track as shown below. The horizontal plane passing through the initial point O is taken as a reference for the gravitational potential energy (At O, PEg =0). Assume that the speed of the ball at point O is v_O = 2 m/s and the ball stops at point B. The height of point B is equal to: hg 20 cm 5 cm 45 cm 6 p B PEg=0
