Plz solve correctly Review | ConstantsA 60° inclined plane of length 0.30 m is positioned at theedge of a table that is 1.0 m high, as shown in (Figure 1).A box is placed at the top of the plane and given a shoveso that it has an initial velocity of 2.0 m/s down theplane. The coefficient of kinetic friction between the blockand the plane is μk = 0.80. (a) Calculate the speed of theblock when it reaches the bottom of the plane. (b) Findthe speed of the block when it is 0.90 m above the floor.(c) Is the total mechanical energy of the block conservedas it moves from the top of the plane to the floor?Write an expression for the sum of kinetic and potential energies of the box at the initial moment.Throughout the problem, we denote the mass of the box as m, the angle of the plane as a = 60°, the length of the plane as d = 0.30 m, the height of the table as H₂ = 1.0 m, theinitial speed of the box at the top of the plane as v₁ = 2.0m/s, and the height from part (b) as H3 = 0.90m. Use the floor as the level of zero gravitational potential energy.Express your answer in terms of some or all of the variables m, a, d, μk, H2, v1, and the acceleration due to gravity g.View Available Hint(s)Hint 1. Potential and kinetic energyThe only conservative forces acting on the box in this problem are the normal force and weight. Though the normal force is indeed conservative, the work done by thenormal force is always zero, so we do not need to include any potential energy for this force, assuming that this energy is always equal to zero. Potential energy of thegravitational force on the surface of Earth equals mgy, where y is the height of an object above the level of zero gravitational potential energy. Kinetic energy, by contrast,does not directly depend on the position of the object and depends only on the mass and speed of the object.Figure1.0 m60%<1 of 1 >0.30 mK₁+U₁ =SubmitΜΕ ΑΣΦ?αβδ€η0ΚλμνΡστ Φ χ@☑AΣΦΨΩ ħ EPrevious Answers Request Answer
