figure shows an downhill plane with the dimensions as H = 15 m, D = 19 m, and an angle ? = 54.14o. Incline has a coefficient of kinetic friction of μk = 1.90.The block of mass m = 2.8 kg starts at labelled point 1 with an initial speed v1 which slides to the labelled point 2. a) What would be the change in gravitational potential energy of the block as it moves from point 1 to point 2?increases ____ J or decreses by ____ J b) Find change in the mechanical energy of the block when it moves from point 1 to point 2?equal but opposite change, or decreases by _____ J, or increases by ___ J c) speed of the block when it arrives at point 2 is _______ the speed at point 1.greater than less than, or the same as, or none. This image depicts a right-angled triangle, often used to illustrate concepts in geometry or physics related to inclined planes.### Diagram Description:1. **Triangle Orientation**: - The triangle is positioned such that one side is horizontal (the base) and another side is vertical (the height).2. **Sides and Labels**: - The vertical side is labeled as **H**, representing the height. - The hypotenuse, labeled as **D**, represents the diagonal side of the triangle. - The base of the triangle is labeled with an angle **θ** (theta) between the hypotenuse and the base.3. **Right Angles**: - At both ends of the hypotenuse, there are right angle markers (squares with numbers 1 and 2), indicating that these are 90-degree angles. - Point 1 is at the base level, and point 2 is at the top of the height.This diagram is useful for explaining concepts such as trigonometric identities, slope, or calculating the length of sides using the Pythagorean theorem.

We know that the work (W) done by a force vector F applied to an object over a displacement ?x is given byW = F(cos?) ?x,where F is the magnitude of the force, and ? is the angle between the applied force and the direction of the displacement. This expression assumes that the force is constant over the displacement ?x. If F is not constant, it can be shown that the work done is equal to the area under the curve force versus position.Based on what above said, calculate the work done by the force versus position represented in each graph (a), (b), and (c) in the figure below.
